STEEL SPECIFICATIONS

For commercial, institutional and industrial constructions, MÉTALEC Doors & Frames uses a wiped finish galvanized steel designed especially to offer the superior durability which is required in steel doors and frames.

Moreover, a wiped finish galvanized steel offers a uniform surface and a very great bond to apply the finish paint. This steel offers better resistance to corrosion than the cold laminated steel, primed and painted. This material is commercially designed under the name of “galvanneal” or “satin coat”.

FINISH

The surfaces where the iron-zinc alloy has been damaged or removed during the manufacturing process, are patched with a primer meeting the “CAN/GCSB 1-GP-181” standard.
All the surfaces have to be free of dust, oil or grease to optimize the paint bond. The paint finish of appropriate type and quality has to be designed for an application on metal.
