Steel
Structural & stainless steel
Load-bearing frames, posts and fasteners
For equipment frames we use hot-rolled St3 profile and tube, followed by galvanizing and powder coating. AISI 304 and 316 stainless steel is used where maximum resistance to moisture and load is needed: fasteners, slides, exposed posts.
Why this material
Steel gives the highest load-bearing capacity at a reasonable price. A properly treated profile lasts 20–30 years without losing strength.
