Buyer Concerns (FAQ）
Q1: What are the main applications for corrugated galvanized sheets?
A: They are widely used for residential roofing, industrial warehouse roofs, agricultural barn sheds, wall cladding, temporary fences, and workshop covers.
Q2: What is the difference between BC and AC width?
A: BC (Before Corrugation) is the flat steel sheet width. AC (After Corrugation) is the actual effective covering width after wave forming.
Q3: How should corrugated galvanized sheets be stored on the job site?
A: Store bundles off the ground in a dry, ventilated place. Keep them covered and tilted slightly so moisture can drain off easily.
Q4: How do I choose the right corrugated profile and width for my project?
A: We supply standard wave and trapezoidal designs. You can select based on your local roofing habit or provide samples/drawings for matching profiles.
