What Kind Of Nails To Use In Pressure Treated Wood

Tree Island Steel's hot-dipped galvanized, ZincGard process ensures complete coverage of the nail shank and caput to reduce corrosion, metting ASTM A153 Class D for utilize in ACQ-treated lumber.

Pressure-treated lumber is treated with Element of group i Copper Fourth (ACQ), an environmentally friendly, h2o-based preservative that is costless of arsenic and chromium.

However, ACQ treated lumber is more than corrosive to metal, so the right fastener is fundamental to a prophylactic, long lasting deck, contend or other outdoor project.

According to Tree Island Steel — a Northward American manufacturer and supplier of premium steel wire and wire products for a broad range of industrial, OEM, commercial structure, residential, and agricultural applications — when nails are exposed to ACQ, a chemical reaction occurs.

This reaction accelerates the corrosion rate of the fastener. Additionally, the organic components of ACQ attract water, further increasing corrosion on the fastener.

The wood treatment manufacture recognizes the corrosive nature of ACQ in relation to fastening systems, and recommends hot-dipped galvanized or stainless steel nails be used. Hot-dipped galvanized nails must encounter American Society for Testing and Materials (ASTM) A153 Class D standards and stainless steel nails should be fabricated from course 304 or 316 — providing maximum corrosion protection.

So, if screws are used for such application, and then they must be rated for ACQ. Tree Isle Steel'due south ZincGard hot-dipped galvanized nails are recommended for employ in outside applications and in ACQ pressure level treated lumber.

The company produces over 400 sizes, shapes, and finishes and all nails meet ASTM F1667, ASTM A153, and ASTM C514 standards.
