During processing period: All the raw material have checked by third party, and also certificate will be neccessary. Tension and strength testing in-house ( we are the only one have this testing machine In Qingdao). All Hand action during cutting will not be allowed,
Before welding: All the welding machine will be checked, and gas must be sufficient to avoid welding line have porosity/ Crators / Cracks . Current will be enough to avoid the welding line not smooth.
Blasting: we make the blasting as 2.0 grade ( australian standard). To ensure there will not rust before painting.
Paint: within 2 hours mustbe painted to gurantee the blasting quality. this project we use EPOXY ZINC RICH PRIMER, TWICE PAINT 80 um. After primer paint, we make Epoxy Mio Barrior Paint 40 paint, that paint will ensure all the components will be not rust during long time shipment on the sea.
Inspection: We make the Ultrasonic Testing In-house, Take record and make report in-house. After we check the components that will be ok. then we ask clients' Inspector come to our factory to check if the quality will be good to loading.
Steel structure is made from organized combination of structural steel members designed to carry loads and provide adequate rigidity. The members of the steel structures are made of steel and are joined by welding, riveting or bolting. These structures are reliable and require less material than other types of structures due to the high strength of steel which are distinguished by the diversity of their shapes and their architectural expressiveness.
Steel Structure Application Fields:
We cater for every market from warehouses, workshops to 4S car exhibition centers, shopping mall, aircraft hangers, poultry & pig sheds, container houses, agricultural & commercial buildings and so on.
1. Cost savings: be inexpensive to manufacture, requires less maintenance than other traditional building methods. Moreover, 98% of all steel structure can be recycled into new steel products without reducing physical properties.
2.Quick erection: steel structures can be erected quickly. The accuracy of steel components speeds up the process and allows monitoring on the management software to complete sooner.
3. Health and safety: Structural Steel is manufactured at the factory and rapid erection on the construction site by skilled personnel making steel structure safe. Industry surveys consistently demonstrate that steel structure is the safest solution. There is very little noise and dust in the process of steel structure erection because structural steel members are fabricated at the factory.
4. Flexibility: Can be modified in the future for new application, loading conditions, vertical expansions and changes in owner’s desires in ways that other framing systems can not accomplish.
