AS/NZS 4357.0 STRUCTURAL LVL: F17 (E14) & F11 (E10) FROM 14-YEAR MILL
72-HOUR BOIL-PROOF SCAFFOLD BOARDS – WBP PHENOLIC, BSI BMP 773486
LONG-SPAN LVL BEAMS DELIVERED TO SITE
SYD/MEL/BNE
Manufactured in our 14-year specialized LVL plant, every F17 (E14) beam is built from select larch & radiata pine, bonded with WBP phenolic resin that survives 72-hour boiling. The result is a predictable, straight member that delivers three times the bending strength of solid timber and meets the toughest clauses of AS/NZS 4357.0.

Need long spans without mid-support? Our Structural LVL is custom cut up to 9.5 m on precision German saws, then kiln-finished to 12 % moisture for minimal on-site shrink. Architects specify it for clear-span auditoriums, car-showroom roofs and mezzanine floors because it behaves like steel at a fraction of the weight.
Termites and Australian weather are no match for our H2/H3 treated LVL. The LOSP dual-treatment penetrates to the core, giving a 50-year durability rating above ground and 25 years in-ground, fully backed by BSI BMP 773486 certification. You build once; the frame stands for generations.
