Quality Control
Yaoguang New Energy Technology Co., Ltd. follows a strict quality control system for every order of C channel steel and cold formed sections. We believe that quality cannot be inspected into a product at the end – it must be built into every step of the process. That is why our quality control starts with raw material selection. We only purchase steel coils from reputable mills and verify each coil against its mill certificate before use. During production, our operators follow written procedures for roll forming, cutting, and punching. They measure dimensions at regular intervals and record the results. If a measurement falls outside the acceptable range, they stop the line immediately and make adjustments. We use calibrated tools including digital calipers, coating thickness gauges, and straightness rulers. All measuring equipment is regularly checked to maintain accuracy.
After production, we inspect each batch again before packing. We check for surface defects, sharp edges, coating uniformity, and dimensional accuracy. We also test sample pieces for strength and coating adhesion when required. Once packed, we inspect the packaging itself – ensuring that steel pallets, wooden crates, or waterproof wrapping will protect the products during sea freight. Our quality control process is not just a checklist. It is a commitment we make to every customer.
