Quality Assurance for Structural Steel Bars
Regular Quality Inspections
- Tensile Test: Measures strength, yield, and elongation.
- Hardness Test: Assesses hardness and wear resistance.
- Re-bend Test: Checks for cracks after bending and immersion.
- Chemical Composition Analysis: Ensures compliance by checking element content.
Extreme Testing
- Impact Test: Evaluates toughness and impact resistance under dynamic loads.
- Fatigue Test: Assesses performance under repeated stress.
- Accelerated Corrosion Test: Exposes to harsh corrosion environments.
- Dynamic Load Test: Simulates extreme dynamic loads like earthquakes or explosions.
If you have specific requirements, we can customize additional tests to meet your needs.
- Protective Coatings: Our steel bars are coated to prevent corrosion and damage during transit. Additional coating options are available upon request.
- Secured Bundling: Bars are securely bundled with steel straps and wooden supports. Finished products are shipped in wooden crates.
- Labeling and Documentation: Each shipment is clearly labeled and comes with detailed documentation for easy tracking.
Structural steel bar performance is influenced by size, fatigue load, environmental conditions, and microstructure.
- Size Effect: Larger diameters slightly reduce yield strength.
- Fatigue Load: Repeated stress cycles cause fatigue damage.
- Temperature: High temperatures reduce strength.
- Corrosive Environment: Acidic or alkaline environments accelerate corrosion.
- Grain Size: Finer grains increase strength and toughness.
- Phase Composition: Different phases affect performance.
Proper storage maintains structural steel bars’ quality and performance:
- Elevated Storage: Use wooden planks or bricks to lift bars off the ground.
- Moisture Protection: Cover with waterproof fabric or plastic sheets.
- Stacking Guidelines: Ensure adequate support to prevent deformation.
- Corrosion Prevention: Apply epoxy, zinc, or paint coatings for surface protection.
