Sky Steel Group supplies hot-rolled and galvanized steel channels (U-Channels, C-Channels, UPN, UPE, and PFC profiles) for building structural framing, foundation shoring, bridge engineering, vehicle chassis fabrication, and industrial machinery bases. Available in depths from 50 mm to 400 mm (2″ to 15″) with standard and custom lengths, our steel channels conform to ASTM A36, ASTM A572, EN 10025 (S235JR/S355JR), JIS G3101 (SS400), and GB/T 706.
Forming, Welding & Structural Advantages
Hot-rolled steel channels feature high load-bearing capacity along the web plane with balanced transverse stiffness, making them ideal for floor joists, wall purlins, roof rafters, and vehicle frame rails. The uniform web and flange thickness ensure reliable weldability under SMAW, GMAW (MIG), and submerged arc welding processes.
The flat web surface allows direct bolted and welded connections with plates, angle brackets, and foundation anchor bolts. Secondary processing such as slotted hole punching, base plate welding, and angle miter cuts can be pre-machined to project shop drawings for rapid on-site assembly.

Where Are Steel Channels (U-Beams) Used?
Hot-rolled steel channels provide high lateral stability, structural strength, and versatile joint connections. They are widely utilized across building construction, civil engineering, foundation shoring, industrial machinery frames, and transport vehicle chassis.
Structural Steel Channel Bundles & Mill Supply
Produced under strict rolling standards with uniform web thickness, clean flange toes, and minimal dimensional tolerances. Stocked in interlocking hexagonal/rectangular bundles bound with heavy-duty wire rods, ensuring safe yard stacking and damage-free crane handling across high-volume structural steel stockyards.
Commercial Building Shoring, Retaining & Facade Framing
Hot-dip galvanized steel channels serve as heavy-duty shoring struts, foundation retaining walls, exterior curtain wall subframes, and structural tie beams. The flat web surface simplifies multi-point bolting and welded gusset plate connections, speeding up structural erection in commercial projects.
Container Export Packing, Fixed Lengths & Color-Coded Ends
Optimized for 20GP (5.8m fixed length) and 40GP/40HQ (11.8m fixed length) container freight. Bundles are arranged nested inside containers with wooden dunnage blocking, and painted with distinct color-coded end markings (blue, green, yellow) for rapid size identification and inventory management at destination ports.
Frequently Asked Questions About Hot Rolled U Channel Steel 100×48×5.3mm, Available to JIS & ASTM A36
1. What is the difference between UPN and UPE steel channels?
The primary difference is the inner flange profile:
• UPN (DIN 1026-1): Standard taper flange channel where the inner flange surfaces have an 8% slope. Flanges are thicker near the web and taper toward the toes.
• UPE (DIN 1026-2): Parallel flange channel with flat, parallel inner and outer flange surfaces. UPE channels feature thinner webs, wider flanges, and higher strength-to-weight ratios, making bolted and welded connections simpler without requiring taper washers.
2. What steel grades and international standards do you supply for channels?
We supply structural channels across all major international standards:
• American Standard: ASTM A36, ASTM A572 Grade 50 (345 MPa yield), and ASTM A992.
• European Standard: EN 10025-2 in S235JR, S275JR, and high-strength S355JR / S355J2.
• Japanese Standard: JIS G3101 SS400 and JIS G3106 SM490.
• Chinese Standard: GB/T 706 Q235B and Q355B.
3. What size range and custom lengths are available?
We supply web depths from 50 mm up to 400 mm (C3 to C15 / UPN 50 to UPN 400). Standard container lengths are 5.8 m (for 20ft containers) and 6.0 m, 11.8 m, 12.0 m (for 40ft/40HQ containers). We also provide custom cut-to-length services with strict length tolerances of ±2 mm.
4. Can steel channels be hot-dip galvanized or primed?
Yes. We provide full surface finishing options:
• Hot-Dip Galvanizing (HDG): Conforming to ASTM A123 / ISO 1461 with average coating thickness of 60–100 µm (450–700 g/m²), providing 30+ years of maintenance-free service in outdoor and marine environments.
• Shot Blasting & Priming: Automatic shot blasting to Sa 2.5 cleanliness followed by epoxy or zinc-rich shop primer (20–40 µm) for corrosion protection during storage and transport.
5. What custom fabrication and machining services do you provide?
We offer integrated pre-fabrication services to reduce on-site labor:
• Precision miter and bevel cutting (45° and custom angles).
• CNC beam line drilling and slotted hole punching for connection bolts.
• Welding of end plates, base plates, stiffeners, and gussets per approved shop drawings.
• Stamping and hard marking of piece numbers for fast on-site erection.
6. How are steel channels bundled and loaded for ocean container shipping?
Channels are tightly nested or bundled back-to-back, bound with heavy-duty wire rod or steel strapping (minimum 4–6 bands per bundle), and fitted with wire lifting loops for crane unloading. End faces are color-painted per size/grade for quick sorting. In container loading, bottom channels rest on wooden dunnage with secure timber bracing to prevent shifting during ocean transport.
