Buyers should specify steel section sizes (e.g., 100x100x3 mm or 150x150x4 mm), full-penetration welding at corner joints, ISO corner castings, design wind and snow loads (e.g., 100 km/h, 1.5 kN/m²), a flat foundation interface, and diagonal bracing. Demand mill certificates, weld inspection reports, and load calculations.
