Product Overview Of ASTM A500 Grade C Structural Tubing
ASTM A500 Grade C Steel Tubing is a cold-formed carbon steel hollow structural section designed for structural construction and mechanical applications. As one of the most widely used North American standard steel tubes, A500 Gr.C hollow sections provide higher strength and better structural stability compared with Grade B, making them ideal for heavy-load structures, building frames, support systems, and engineering equipment. Brisk Steel supplies high-precision ASTM A500 Grade C square tubing, rectangular tubing, and round structural tubing with consistent chemical composition, stable mechanical performance, and strict dimensional tolerance control.
Mainstream manufacturing process:
Hot-rolled or cold-rolled steel strip → Cold-forming into a square shape → Longitudinal high-frequency welding → Weld seam leveling → Cut-to-length → Straightening
Standard & Product Definition
ASTM A500 is the standard specification for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. Grade C is upgraded from Grade B with improved yield strength and tensile strength, specially produced for projects that require stronger structural bearing capacity and higher safety factors. All our A500 Gr.C steel tubes are manufactured fully compliant with ASTM A500 standard requirements and can be provided with official Mill Test Certificates for engineering inspection and project acceptance.
Weld Seam Quality
ERW rectangular tube has a longitudinal weld seam. The weld bead can be scarfed (removed) for smooth surface as required.
- Standard weld: suitable for general structural use
- Scarfed weld: preferred for high-pressure, precision or aesthetic applications
- Weld integrity test: eddy current test can be applied to detect weld defects For critical projects, we can supply non-destructive testing (NDT) reports.
Available Shapes & Size Range
Brisk Steel provides full-series ASTM A500 Grade C structural steel tubing in three common shapes to meet diverse engineering design needs:
- Square Steel Tubing: Widely used for building columns, supports, and frame structures
- Rectangular Steel Tubing: Ideal for equipment frames, chassis, and architectural structures
- Round Steel Tubing: Suitable for general structural and mechanical support applications
Custom sizes, wall thicknesses, and cut lengths are available according to customer drawings and project requirements.
Features of ASTM A500 Grade C Structural Tubing
ASTM A500 Gr.C steel tubing has become the preferred structural hollow section for global engineering buyers due to its comprehensive performance advantages:
- Higher structural strength: Higher yield strength than Gr.B, suitable for heavy-load engineering projects
- Precise dimension tolerance: Cold-formed process ensures straightness, flatness, and section uniformity
- Excellent processing performance: Easy to weld, cut, bend, drill, and punch for deep processing
- Stable quality consistency: Strict raw material inspection and online production monitoring
- Flexible surface treatment: Available in black finish, oiled anti-rust, and hot-dip galvanized finish
- Complete certification support: MTC provided, third-party inspection (SGS/BV/Intertek) acceptable
Surface Treatment & Custom Service
To adapt to different environmental and construction needs, we provide multiple surface solutions for ASTM A500 Grade C steel tubing: black oiled finish for temporary anti-rust during transportation, hot-dip galvanized treatment for outdoor anti-corrosion use, and customized cutting, deburring, punching, and bending processing. Custom lengths and special specifications are supported for personalized project requirements.
FAQ
Q: What is ASTM A500 Gr.C steel tubing used for?
A: ASTM A500 Grade C steel tubing is a high-strength structural hollow section mainly used for building frames, structural supports, warehouse racking, mechanical equipment frames, and transportation structural systems.
Q: What is the difference between A500 Gr.B and Gr.C?
