29u Steel Arch
This 29U steel arch is a passive coal mine support structure engineered for load-bearing in underground mining applications. The profile uses 20Mnk material, a manganese-based alloy steel selected for its tensile strength and compressive resistance, with the U-shape geometry optimised for lateral stability in roof support. The supplier offers configurations as single beam, double beam, treble beam, and grade beam variants to suit different tunnel widths and load distributions.
20Mnk steel is a standard grade for mine supports in China, delivering a typical yield strength of 355 MPa and elongation above 20 percent for toughness in dynamic rock conditions. The 29U designation refers to the profile height in centimetres, with a standard flange width of 80 mm and web thickness of 8 mm for this class. Surfaces are delivered in a hot-rolled, uncoated finish as typical for underground use, though galvanised or painted options are available on request.
Primary buyers are coal mine operators and tunnelling contractors sourcing structural supports for immediate roof stabilisation. Common trade terms include bulk shipping in 20-foot containers, with MOQ and lead time to be confirmed directly with the supplier. The arches are supplied as straight lengths, typically 2.5 m to 6 m, and are installed in sets with connecting plates and bolts for continuous support lines.

Sourcing 29u Steel Arch from Henan Zongxiang Heavy Industry Import And Export Co, .ltd. - China Import Guide
Before ordering, verify the exact chemical composition and mechanical properties of the 20Mnk steel, as these directly affect the arch’s performance under load. Request mill test certificates and third-party inspection reports to confirm compliance with GB/T 1591 or equivalent standards. Ensure the profile dimensions match your mine’s support design requirements.
Confirm logistics details such as lead time, Incoterms, and packaging for bulk shipments. The 29U arches are typically shipped in 20-foot containers, with lengths nested to optimise space. Clarify whether the supplier provides loading diagrams and securing protocols to prevent damage during transit. Payment terms should be agreed in advance, with consideration for letters of credit or advance deposits for first-time orders.
Quality checks should include dimensional verification, visual inspection for surface defects, and mechanical testing of sample pieces. For underground use, inspect the arches for straightness and absence of cracks or laminations. Request documentation such as material traceability records, test certificates, and compliance declarations to ensure the product meets your safety and performance standards.
