The "All in One" Wall System

demising wallThe SteelSpan “all in one” panel is an innovative modular wall system that does not require a framing system. Its innovative design is ideal for effectively and economically dividing your plant space from floor to roof or for creating ceilings and roofs in commercial and industrial buildings. The non-combustible panels are constructed of a polyurethane insulating core with excellent insulation values. SteelSpan panels are light weight, yet structurally strong and feature a one-piece construction that makes assembly quick and cost effective.

Structural Integrity

Despite their light weight, SteelSpan Panels are structurally strong enough for greater heights. They range in thickness from 3" to 6" and are constructed of G-90 galvanized steel with a secure tongue and groove connection.
