Materials & finishes

The example sheets name a material and a finish for each piece. Here is what those words mean, so you can name them in your own brief.

Material

What the sheets use

Steel tube: Round or hollow section used for rails and frames. Seen on: Mezzanine guardrail bay.
Flat bar: Flat strip steel, used with tube for a rail run. Seen on: Mezzanine guardrail bay.
Square steel tube: Square hollow section for rigid frames. Seen on: Doorway canopy frame.
Steel plate: Flat plate, cut and drilled for bases and mounts. Seen on: Equipment base rebuild.

Finish

Joints ground flush, uncoated: Weld joints are ground level with the surrounding surface and the steel is left uncoated. Seen on: Mezzanine guardrail bay.
Mill surface, ready for coating: The steel keeps the surface it has from the mill, ready for whatever coating you plan. Seen on: Doorway canopy frame.
Edges deburred: Sharp burrs left by cutting and drilling are removed from the edges. Seen on: Equipment base rebuild.

Material, fit, and finish are settled with you on each job. These are examples of the kind of thing a job can name.

In one table

Each example sheet pairs one material with one finish for one use.
