The recent transition and changes within the treated wood industry have had a huge impact on fasteners. The new alternative treatments such as ACQ, Copper Azole, etc. are proving to be more corrosive than many industry experts originally thought. There are still issues and concerns over which nails and screws will work with the new copper based treatments.
The industry had over twenty years of experience with the CCA treatment and always recommended hot-dipped galvanized or stainless steel for use with their wood products. The recently published 2006 International Building Code states “Fasteners for preservative-treated and fire-retardant-treated wood shall be of hot dipped zinc-coated galvanized steel, stainless steel, silicon bronze or copper. The coating weights for zinc-coated fasteners shall be in accordance with ASTM A 153.” Maze Nails produces genuine double hot-dipped galvanized nails which meet and actually exceed the all important ASTM A 153 specification for hot-dipping. The exclusive STORMGUARD® process insures a thick uniform coating of zinc providing a good degree of corrosion-resistance for routine, residential inland applications that dry out quickly and get sufficient air circulation.
When to use hot-dipped fasteners and when to use stainless steel seems to be the question in our industry. In their newly released 2006 catalog, Simpson Strong-Tie provides an easy to understand guideline for selecting the proper connectors and fasteners with the new treated lumber products. This good information can be accessed at Pressure-Treated Wood FAQs page. In a nutshell, you should know the chemical retention level of the wood treatment you are using. For wood with actual chemical retention levels greater than 0.40 pcf for ACQ, 0.41 for CBA-A or 0.21 for CA-B (Ground Contact), stainless steel fasteners and connectors are recommended. The treated wood suppliers provide this vital information on their wood products. Another important guideline is to use stainless steel fasteners when installing stainless steel connectors. When using hot-dipped galvanized connectors, use only genuine hot-dipped fasteners which meet ASTM A 153. It is important NOT to mix different metals.
Maze Nails continues to introduce new products to meet industry trends and new applications. With the popularity of cellular PVC products such as AZEK®, Kleer™ and Koma™, Maze now offers painted nails in both coils and hand driven to apply these attractive trim products. Maze also offers pre-finished painted nails to match all of the James Hardie colors for their Colorplus® Technology fiber cement siding and trim.
Maze Nails always promotes top-quality genuine hot-dipped galvanized or stainless steel nails as being well worth the additional expense. The few additional dollars spent for the “right fasteners” can make a huge difference in the lifetime of the project. With the new, attractive and more expensive sidings, decking and trims, it just doesn’t make sense to use cheap nails that will fail prematurely.
