Q:Our company intends to purchase a large quantity of bend pipes. The first order will be a small sample order. If the quality is good, I believe we will continue to purchase in large quantities. Please help me find a reliable supplier.

I purchased galvanized steel sheets from their company earlier this year. They provide raw material certificates with clearly stated chemical composition and mechanical properties (yield strength, tensile strength, etc.), fully compliant with national standards. The adhesion between their material substrate and zinc coating is excellent; as long as your mold and process parameters are appropriate, there have been almost no instances of large-area zinc coating peeling or noticeable micro-cracks during bending.

If you're still concerned, I strongly suggest they send a sample for testing first. That's what we did; we bent it a few times, tested the zinc coating, and once the results came back, we had a clear understanding of its quality.
