Material requirements for steel structure fabrication
Quantity : 1000000 Price : $35-$80 per sqm
The steel structure system has comprehensive advantages such as lightweight, easy installation, short construction period, good seismic performance and less environmental pollution. These advantages mostly come from the raw materials of the steel structure. The quality of the material determines the quality of the steel structure. In this issue, the editor and everyone divide the material requirements for steel structure production. I hope it will be helpful to friends who do steel structure engineering.
1. The steel materials, welding materials, coating materials, and fasteners used in the steel structure should have quality certificates and must comply with the design requirements and current standards.
2. In addition to the quality certificate issued by the manufacturer, the raw materials entering the factory shall be witnessed on-site, sampled, submitted, inspected, and accepted under the witness of Party A and the supervisor according to the contract requirements and relevant current standards. Good inspection records. And provide inspection reports to Party A and the supervisor.
3. Substitute materials should be submitted by the manufacturer in advance with an application letter (technical approval form) with a material certificate, after submitting to Party A and the supervisor for review, the design unit can only be used after confirmation.
4. It is strictly forbidden to use electrodes with peeled skin or rusty welding core, damped or agglomerated flux, or rusted welding wire. The surface of studs used for stud welding shall not have defects such as cracks, dents, and burrs affecting the use.
5. It is strictly forbidden to use high-strength bolts that are corroded, stained, damp, bruised, and mixed. The materials are used well, and there are few troubles in the later stage. The selection of good materials for the steel structure not only reduces the maintenance expenditure in the later stage but also extends the life of the building.
