Treated Lumber

H.M. Stauffer has been involved in the wood preservative business since 1975. We are an authorized licensee of Lonza Wood Protection. Our pressure-treated products are sold under the well-known brand name “Wolmanized® Outdoor® Wood” and are available in two distinct formulations:


Wolmanized EraWood™: a nonmetallic, carbon based, low impact preservative for above-ground use

 

Wolmanized µCA-C: a reduced copper preservative utilizing micronized technology for both ground-contact and above-ground use

 

Both products are backed by lifetime limited warranties against termites and fungal decay. An extensive in-house QC program coupled with the use of SPIB as an independent third-party inspection service means you can expect a properly treated product delivered year round.

Kiln-dried after treatment (KDAT) material is also available for immediate shipment in a variety of lengths, sizes, and grades.

Treating Service Only (TSO) is available for those customers preferring to supply their own wood.

Engineers at the Good Housekeeping Institute have deemed Wolmanized Outdoor Wood worthy of its seal - learn more
