INTERNATIONAL QUALITY STANDARDS IN CONSTRUCTION BOLT MANUFACTURING
A reputable construction bolt manufacturer in Vietnam must not only meet domestic demands but also have export capabilities. This requires strict adherence to the following technical standards:
2.1. American Standards (ASTM)
- ASTM A325, ASTM A490: Applied to high-strength bolts that bear heavy loads.
- ASTM F1554: Designed for special structural steel applications.
2.2. European Standards (DIN, ISO)
- ISO 898-1: Specifies the strength and mechanical properties of bolts.
- DIN 931, DIN 933: Widely used in construction and mechanical engineering industries.
2.3. Japanese Standards (JIS)
- JIS B1180, JIS B1186: Particularly common in projects utilizing Japanese technology.
By adhering to these standards, construction bolts not only achieve high durability but also ensure load-bearing capacity, corrosion resistance, and stability in harsh environments.
