1. Special steel: Mainly cold-rolled precision steel pipes and corrosion-resistant alloy pipes, using vacuum degassing technology to improve material purity, with a yield strength of more than 800MPa.

2. New functional materials: including high-strength waterproof steel for construction, which uses nano-coating technology to improve anti-penetration performance by 40%, suitable for the high temperature and high humidity environment in Southeast Asia.

3. Processing services: Provide customized processing such as laser cutting and coil forming, and support multi-national standard certification such as ASTM/EN/DIN.

News 6: Hot-rolled vs. cold-rolled - Shengqiang Steel analyzes the golden rules for selecting steel for construction

Aiming at the blind spots of construction customers in understanding hot-rolled and cold-rolled steel, Shandong Shengqiang launched the "Steel Selection Manual for Building Structures", with the core conclusions:

1. Strength: The yield strength of cold-rolled SPCC (280MPa) is higher than that of hot-rolled Q235B (235MPa), but the ductility is 15% lower;

2. Cost: The hot-rolled ton price is 8%-12% lower, suitable for non-exposed structures;

3. Precision: The cold-rolled thickness tolerance is ±0.05mm, which is better than the hot-rolled ±0.15mm.

The manual has guided a commercial complex project in Southeast Asia to save $3 million in material costs and won the "Best Technical Partner" award from the owner.
