Before raw materials are put into storage, component analysis, mechanical performance testing and appearance inspection are conducted on various steels, connectors, welding materials and other items. The steel quality certificate is verified to prevent unqualified raw materials from entering the production link.
During the production and processing process, a combination of first article inspection, regular patrol inspection and random sampling inspection is adopted to focus on controlling the cutting accuracy, welding quality and component assembly deviation of steel structures. Key links such as welding joints, weld thickness and anti-corrosion coatings are subject to 100% full inspection. Deviations in the production process are corrected in a timely manner to ensure that the processing accuracy and craftsmanship meet the standards.
Before finished products leave the warehouse (or project delivery), comprehensive performance testing is carried out, including dimensional accuracy review of steel structure components, weld flaw detection, anti-rust and anti-corrosion performance testing, and bearing capacity testing. For large-scale steel structure components, additional deflection, strength and stability testing are conducted. All products and processing achievements must obtain qualified test reports and pass multi-party acceptance before being put into storage, shipped or delivered on site.
The production and testing equipment covers advanced models in the steel structure industry: it is equipped with metallographic analyzers, tensile testing machines, impact testing machines, salt spray test chambers and high-precision coordinate measuring machines. For welding quality, ultrasonic flaw detectors and X-ray flaw detectors are introduced; for large-scale steel structure components, laser rangefinders and structural load testing equipment are provided. At the same time, special testing tools such as coating thickness gauges and hardness testers are equipped, fully covering the testing needs of raw materials, production and processing, and finished product delivery links. This ensures that each link has accurate data support, and lays a solid foundation for the quality of steel structure products and engineering processing with strict quality inspection standards, helping domestic and foreign customers achieve worry-free acceptance and safe use.
