Pressure Treated Lumber Grades

What Is Strain Handled Lumber?

Defending wooden in opposition to rot and bugs has been finished for hundreds of years. Some varieties of timber have pure skills whereas others want a lift. In historical occasions the Greeks used olive oil, the Romans tar, and others used pitch or lye. Within the Nineteenth-century railway corporations used creosote to coat railway ties and timbers for bridges. Trendy chemical baths and pressurization started within the early half of the twentieth century.

Immediately, stress handled lumber for residential use is often pine, spruce, or fir that has been immersed in a water-based chemical tub of preservatives. Pressurization then forces the liquid deep into the wooden. The wooden then is dried naturally or in a kiln to evaporate the water out, leaving the preservatives behind.

Totally different chemical compounds have been used within the preservative tub, with modifications being made to restrict well being dangers to people and animals. Oil-based and creosote therapies are nonetheless used however for the reason that preservatives leach out over time and with warmth, they’re thought-about too messy or hazardous for residential use. These and different therapies are used for industrial functions as a substitute.

Advantages of Strain Handled Wooden

Strain remedy is an inexpensive various to costly naturally rot-resistant lumber. The preservatives present safety in opposition to rot, bugs, mould, and fungi, so the wooden lasts longer. Handled wooden is constructed from robust evergreen species making it appropriate for many constructing initiatives.

The wooden weathers higher than untreated wooden and received’t grey or discolor as rapidly. Strain handled wooden may also be stained or sealed to reinforce its coloration and for added safety.

How Is Strain Handled Wooden Produced?

Strain remedy of lumber has come a great distance previously 100 years. The present course of is generally computerized and mechanized utilizing trendy expertise. The method is comparable for treating milled lumber, plywood, posts, or utility poles in opposition to rot and bugs.

The remedy doesn’t penetrate deeply into the wooden as a result of impermeable nature of the wooden cells. Nevertheless, sufficient will get into the wooden to offer a shell of safety that may’t be matched with a brush. Some wooden goes via a machine that incises small cuts into the surfaces for deeper chemical safety.

Remedy Course of

The dry wooden is loaded right into a remedy cylinder which is then sealed and depressurized to hoover as a lot air as potential from the wooden cells. The chamber is then flooded with a diluted chemical resolution, and hydraulic stress utilized for 20 to 60 minutes to power the answer deeper into the wooden. The vacuumed cells extra readily take in the answer for higher penetration.

On the finish of the pressurized interval, the answer is pumped out and saved to be used on the following batch. A fast depressurization cycle then removes any extra from the wooden earlier than it’s faraway from the remedy cylinder.

The handled wooden is then taken to the yard to dry naturally or to the drying kilns earlier than transport to the retailer. Because the wooden dries, the preservative is left behind to guard in opposition to bugs, mould, mildew, fungal progress, and decay.

Varieties of Wooden Preservatives

Totally different chemical options are used to create handled lumber. Here’s a checklist and outline of a few of them.

Chromated Copper Arsenate (CCA)

CCA is a combination of chromium, copper, and arsenic that turns wooden inexperienced. It was broadly used as a preservative from the mid-Thirties to 2004. A research by the EPA in 2000 deemed it too hazardous for residential use, and in 2003 the lumber business agreed to cease utilizing it for residential functions. CCA remains to be used for industrial functions in the present day.


Borates are sodium salts utilized in water-based stress remedy options. They don’t discolor the wooden and shield in opposition to bugs, molds, mildew, and fungi. Sadly, the water-soluble nature makes them prone to leaching out in wet or moist areas, or close to standing water. Nevertheless, they make a great resolution to be used in arid or dry places.

Micronized Copper Azole (MCA)

MCA is an environmentally pleasant water-based preservative thought-about secure for people and animals and is an alternative choice to CCA. Nevertheless, it shouldn’t be used the place it is available in contact with meals or animal feed.

The answer protects in opposition to bugs, mould, mildew, fungus, and decay, and turns the wooden a lightweight brown hue. MCA can be utilized inside or out, above floor, in-ground, or in fresh-water contact residential areas.

Alkaline Copper Quaternary (ACQ)

ACQ is one other environmentally secure preservative composed of soluble copper and both quaternary ammonium alkyl or substitute compounds. The answer protects the wooden from rot, bugs, fungus, mould, and mildew, and in addition turns the wooden a brown tone. Much like MCA, the handled wooden shouldn’t be utilized in contact with meals or animal feed.

Professional Notice: All copper-based wooden preservative options will corrode unprotected iron and metal brackets and fasteners. Use tar paper or bituminous tape to guard steel brackets and ho-dipped galvanized or stainless-steel fasteners, or these specifically coated to forestall corrosion by wooden preservative chemical compounds.

Moreover, all cuts and drilled holes must be handled with preservatives to forestall injury to uncovered untreated wooden.

Makes use of for Strain-Handled Wooden

Pressure treated wood deck

Strain handled wooden has many out of doors makes use of and even is utilized in some indoor places, particularly the place moisture could also be a priority. Various kinds of handled lumber are utilized in many facets of residential, business, and industrial development the place moisture or floor publicity might happen.

From the cedar shakes, facia, and trim of a home to the sill plate and wood foundations or helps, stress handled wooden is frequent in residential development. It’s used to construct exterior stairs, for posts, sheathing, siding, porches, decking, and railings too.

Many properties have fences, retaining partitions, and backyard containers constructed of handled wooden, and even the wood utility poles supplying energy and communications are stress handled.

Basements and bogs are different areas the place stress handled wooden can be utilized to border inside partitions to guard in opposition to moisture, mildew, and mould injury. Some lumber can also be handled for fireplace safety and used all through totally different areas of residential, business, and industrial development. There are numerous different makes use of for pt lumber, together with docks, boathouses, sheds, boardwalks, play constructions, gazebos, and the checklist goes on.

Varieties of Strain-Handled Wooden

Strolling right into a lumberyard or retailer could be a daunting expertise. Many DIYers and even some professionals aren’t conversant in the several types of stress handled wooden and their makes use of, or that the knowledge is on the end-tag stapled to the board. Deciding on the proper sort of handled wooden for a venture typically depends upon how and the place will probably be used.

Strain handled lumber is split into differing kinds based mostly on the ‘retention stage’ or quantity of preservative retained within the wooden after remedy. The retention stage is measured in kilos of chemical per cubic foot of wooden (pcf). The longer the wooden is within the stress chamber, the better the content material of chemical preservatives pressured into and retained within the wooden.

Strain remedy doesn’t make the wooden stronger or weaker, simply extra immune to insect and moisture injury. The quantity of chemical retained determines how resistant the lumber will likely be. The American Wooden Safety Affiliation (AWPA) units the requirements for the retention stage required for the totally different chemical preservative compositions for particular varieties of use.

The results of having a unified score means the end-tag on lumber identifies how nicely the wooden will rise up in numerous situations, whatever the chemical cocktail it’s been uncovered to. There are six several types of stress remedy scores, with totally different classes in a few of them. The kind identifies the quantity of chemical retention which in flip determines how or the place to finest use the lumber.

Above Floor

Use UC3A stress handled lumber for above floor exterior initiatives. The wooden must be at the least 6-inches above the bottom, have good air circulation and drainage, and the parts can simply get replaced.

Floor Contact

Floor contact means something inside 6-inches of the bottom or involved with the bottom, foliage, grasses, or over water or moist areas. It could have poor drainage and air circulation, or like a sill plate, is tough to restore or keep. Strain handled wooden for floor contact generally has twice the chemical retention stage as above floor rated lumber. UC3B or UC4A are finest for floor contact use.

In-Floor Contact for Crucial Use

Strain handled wooden used for in-ground or crucial use has a better retention stage than timber used for above or floor contact. Use in-ground sort lumber the place there’s a better danger of decay or extreme environmental publicity, or for crucial structural parts like basis posts, publicity to recent or groundwater, or utility poles.

The really helpful sort of handled wooden for in-ground use is UC4B and UC4C; UC4B has the next retention stage than decrease graded sorts, and UC4C has much more.

Marine Grade

Lumber stamped #2 grade is often used for framing, lintels, rafters, trusses, joists, beams, and fencing. Structurally, an SPF #2 2×8 can be utilized to span distances of 14’-11”.

  • In look grade, the planks are 66% clear wooden.

#3 Grade Structural

Lumber with extra checks, splits, wane, well-spaced bigger knots and holes, and a grain slope of 1 in 4 are stamped #3 or development grade. The wooden is often used for gentle development or framing the place it isn’t seen, or for bracing, packaging, and transport functions. Structurally, an SPF #3 2×8 can be utilized to span distances of 12’-4”.

  • In look, it’s at the least 57% away from defects.

Building Grade

Building grade generally refers to #1 grade lumber. It’s used for all areas of residential development from load bearing to trim.

Normal Grade

Normal grade lumber has extra defects and knots and is #2 structural grade wooden. Generally used for joists, trusses, and different load-bearing purposes.

  • The wooden is 43% clear for look ‘grading’.

Utility Grade

Utility grade is #3 grade lumber and has even fewer restrictions relating to knots and defects in comparison with different grades. It’s not as robust as the opposite grades and is often used for the place it received’t be seen, and lightweight framing functions corresponding to bracing, crates, and pallets.

  • For look, it should be 29% away from defects.

Look Grade

Premium and choose classifications and the proportion of clear wooden are look grades utilized by some mills and retailers. The looks doesn’t have an effect on the structural grade, it simply is superficially extra interesting. The look of the wooden is barely essential whether it is extremely seen, corresponding to deck boards, railings, and different seen structural members.

What’s the Finest Strain Handled Wooden for Decks?

Species and Sizes Of Strain Handled Wooden

Strain handled lumber is available in a wide range of lengths, widths, and thicknesses and from totally different species of softwood. The kind and dimension affect the power of the timber.

Totally different Sorts of Softwoods That Are Strain Handled

The sorts of softwood accessible in numerous geographic areas typically decide what species is obtainable for stress remedy. Southern yellow pine (SYP) may be very robust and is frequent within the japanese U.S. A mix of spruce, pine, and fir (SPF) dominate a lot of the northern U.S. and japanese and central Canada and isn’t as robust as SYP.

Douglas fir, fir, and hemlock dominate within the western U.S. and Canada, with Douglas fir rating the strongest of the generally milled and handled softwoods, whereas the fir and hemlock are barely stronger than SPF.

Species of Wooden

The principle tree species used within the manufacture of stress handled lumber are softwoods that regionally predominate within the mill space. Southern yellow pine within the japanese U.S., spruce pine and fir within the northern U.S. and eastern-central Canada, and Douglas fir, fir, and hemlock within the western U.S. and Canada.

Southern Yellow Pine

Longleaf, shortleaf, loblolly, and slash are a few of the native southeastern pines which are categorised as SYP. It’s a very robust and stiff softwood, and dense too. It holds nails, screws, and different fasteners nicely, and is often utilized in residential, industrial, and business development. SYP holds nearly 85% of the U.S. stress handled market. It has a novel broad grain mobile construction that enables for uniform and deep penetration of chemical preservatives.

Douglas Fir

Douglas fir has a decent shut grain cell construction making it stronger and fewer vulnerable to warping and twisting than pine. Nevertheless, the tight grain additionally makes it much less receptive to stress remedy. Older progress wooden is best however costlier and tough to search out.


Strain handled lumber is obtainable in 1”, 5/4”, 2”, 4”, and 6” nominal thicknesses, and widths as much as 12”. Handled posts or ties available at yards and shops are 3×5, 4×4, and 6×6; 8×8 can also be accessible however could also be a particular order.

The stamp identifies:

Wooden Species

D Fir-L or Doug Fir for Douglas fir or larch (L)

SYP for Southern yellow pine

H-F, Hem-fir, or Hem for hemlock-fir or hemlock

S-P-F for spruce, pine, or fir

Grade of Lumber

The grade of lumber is famous – SS, #1, #2, #3, or STUD – and the value displays the standard.

Moisture Content material

The quantity of moisture within the wooden on the time of milling is famous. Unseasoned or inexperienced lumber has a moisture content material of 19% or better and topic to shrinkage and warping because it dries. It’s stamped S-GRN for surface-green or AD for air-dried. Lumber that’s KD (kiln-dried) or S-DRY (surface-dry) has a moisture content material that’s decrease, between 16% and 19%.

Lumber that’s imported or for export requires the designation KD-HT, which implies it has been kiln-dried and heat-treated to kill bugs. KD and KD-HT are sometimes costlier and fewer prone to warping and shrinkage. MC-15 identifies lumber as having 15% or much less moisture content material.

Registered Emblem or Image

All lumber should determine the affiliation or company accredited with overseeing the grading – MLB is the Maritime Lumber Bureau.


The certification identifies the grade guidelines used to grade the lumber – for instance, ALSC is the American Lumber Normal Committee and NLGA is the Nationwide Lumber Grades Authority.


A quantity that identifies the mill the place the lumber was produced. It typically hyperlinks with the brand or image of the affiliation that oversees the grading at that mill.

There could also be a secondary stamp that identifies the visible grade as Premium or Choose A, B, C, or D.

Strain handled lumber additionally has an end-tag caught or stapled to 1 finish. The tag identifies its correct use – Above Floor, Floor Contact, and so forth. There’s a barcode with product info, registration emblem or image noting the requirements adopted, and the use class (UC4A for Floor Contact).

The kind of preservatives, retention stage, and yr it was handled are recognized on the label. The accredited inspection company, producer, and plant are additionally generally on the label however could also be accessible within the bar code.

Ideas for Working with Strain Handled Wooden

Working with stress handled lumber is much like working with untreated planks. Gloves shield in opposition to slivers and water-soluble chemical compounds; it’s also advisable to totally wash arms earlier than consuming or ingesting. Whereas most residential stress handled lumber is deemed secure to be used, mud and particles can nonetheless be dangerous.

Carrying security glasses or a defend protects the eyes from mud and particles when drilling, slicing, or sanding, and a mud masks will forestall inhalation of mud and chemical compounds. Handled wooden will shrink because it dries and broaden when moist and will purchase floor checks and cracks over time. Overly dry wooden typically wants a pilot gap earlier than fastening to forestall splitting.

Strain handled wooden might require a number of weeks and even months to dry earlier than it’ll take in stain or paint. The chemical remedy makes the wooden resists bugs, mould, mildew, and decay however not moisture-proof. It must be handled each 2 to three years (relying on the setting) to guard it from moisture injury.


Strain handled lumber has been handled with a chemical resolution to guard it from bugs, mould, mildew, and decay. There are several types of remedy and lumber grades for various makes use of.

I hope you have got a greater understanding of what stress remedy means and which grade and sort is finest on your venture.
