Align the frame and secondary members before sheeting. Gutters, corners and window flashings need details, not a site-cut scrap. Stiffen openings so leaks do not start at lights, doors and equipment holes.

A profile change often changes purlin spacing. Do not cut before approval. Export jobs also check the agreed profile and packing, not colour alone.

Appearance and weathering are one package. A frame price that omits secondary members and trims will stop the sheeting sequence.

State roof, wall, openings and drainage together. No single profile or brand is set here.
