Application of Steel U Beam:
Tracks & sliders for machines, doorways, etc.
Posts and supports for building corners, walls & railings.
Protective edges for walls.
Decorative elements for constructions like ceiling channel system.
Frames or framing material for construction, machines.
A load is applied at the center of a beam using weights, and the resulting midspan deflection is measured. The elastic stiffness of the beam is determined and compared to published values for various beam materials and cross sectional shapes.
U beams (channels) are widely used in construction, machinery manufacturing, and automotive industries. The U-shaped cross-section provides excellent bending resistance in one direction while remaining cost-effective.
Key advantages: Easy connection to other structural members, convenient for welding and bolting, excellent load distribution, economical pricing compared to H/I beams for lighter applications. Ideal for door frames, window frames, purlins, and light structural supports.
Standards: JIS G3192 (Japan), EN 10025 (Europe), GB/T 707 (China), ASTM A36 (US).
Available grades: Carbon structural: Q235B, SS400; Low alloy: Q345B, Q355B; High strength: A572 Gr50. Custom grades available with minimum order quantity.
Quality control includes:
(1) Raw material inspection
(2) In-process monitoring of dimensions
(3) Dimensional inspection of every beam (depth, flange width, web thickness)
(4) Surface quality inspection
(5) Mechanical testing (tensile, yield)
(6) Chemical composition verification
All beams come with Mill Test Certificates (MTC) per EN 10204 3.1.
Packaging: Multi-piece bundles secured with steel straps, wooden dunnage for surface protection, waterproof covers for overseas shipments.
Loading: 20ft container: 18-22 tons; 40ft container: 25-28 tons.
Shipping terms: FOB Tianjin/Qingdao, CIF, CFR, DAP available. For project orders, we offer sequence loading for easier on-site installation.
Standard lead times: Stock items: 3-7 days; Regular orders: 15-25 days; Custom specifications: 25-45 days.
We maintain strategic raw material inventory to mitigate supply chain risks. For urgent orders, our express channel offers priority scheduling. Real-time order tracking available through our sales team.
Yes, we offer: Custom lengths from 1m to 18m, fixed random lengths or specific lengths.
We provide Mill Test Certificates (MTC) per EN 10204 3.1/3.2. Third-party inspection by SGS, BV, or ABS can be arranged upon request. Our facility is certified to ISO 9001:2015.
The dimensions do not exceed the acceptable tolerance of±6 mm in either of the primary axes
