Quantity
The A-Grade Rectangular Exercise Tube is a high-performance rectangular steel tube manufactured from premium low-carbon carbon steel (CS), complying with ASTM standards for superior strength and durability. Standard dimensions are 25.4×50.8×2 mm with 6-meter lengths (customizable), formed through welded processes and featuring oiled surfaces for rust prevention. This A-Grade Rectangular Exercise Tube is widely used in construction structures, infrastructure, machinery manufacturing, industrial equipment, fitness equipment, shelves, and furniture, delivering stability and cost-effectiveness for engineering projects.
A-Grade Rectangular Tube Surface Treatment Options
Surface treatments for the A-Grade Rectangular Exercise Tube directly impact corrosion resistance, service life, and application environments. The standard anti-rust oil coating can be upgraded to hot-dip galvanizing (zinc coating ≥60g/m²) or paint/powder coating for enhanced protection.

1. Standard Oiled Surface Treatment
Process:
After cold-forming, welding, and straightening, the A-Grade Rectangular Exercise Tube is coated with rust-preventive oil (mineral or specialty agents) to form a temporary protective film against oxidation during transport and short-term storage.

After cold-forming, welding, and straightening, the A-Grade Rectangular Exercise Tube is coated with rust-preventive oil (mineral or specialty agents) to form a temporary protective film against oxidation during transport and short-term storage.
Advantages:
- Cost-effective: Lowest price point, ideal for short-term protection (3-6 months).
- Cost-effective: Lowest price point, ideal for short-term protection (3-6 months).
- Processing-friendly: No degreasing required prior to welding or cutting (oil film compatible with most welding methods).
- Applications: Indoor dry storage or short-term projects using A-Grade
Rectangular Exercise Tube.
Limitations:
- Requires additional finishing (e.g., galvanizing) for prolonged outdoor exposure.
- Requires additional finishing (e.g., galvanizing) for prolonged outdoor exposure.
2. Hot-Dip Galvanizing (HDG)
Process:
The A-Grade Rectangular Exercise Tube is immersed in molten zinc (450°C) to create a zinc-iron alloy layer (≥60g/m²) meeting ASTM A123/A153 standards.

Steps:
1. Degreasing: Removes surface oils.
2. Acid pickling: Eliminates scale with hydrochloric acid.
3. Galvanizing: Forms uniform zinc coating.
4. Passivation cooling: Seals protective layer.
