ZSJH
Hot Rolled Steel Sections are essential structural materials used to construct strong, efficient and durable load-bearing systems. Available in several cross-sectional shapes, these products can be used as columns, beams, braces, supports, frames and connection components.
ZSJH Steel provides factory-direct supplies of hot rolled H sections, I sections, channels, angles, T profiles and flat bars. We support both bulk material orders and complete project material packages.
Products can be supplied in standard lengths or processed according to structural drawings, fabrication drawings and bills of materials.
、
| Section | Structural Characteristics | Common Uses |
|---|---|---|
| H Section | Wide flanges and high sectional efficiency | Columns, primary beams and heavy frames |
| I Section | Excellent resistance to vertical bending | Floor beams, roof beams and equipment supports |
| U Channel | Open profile suitable for framing and reinforcement | Frames, supports, edge members and bases |
| Equal Angle | Two legs of equal width | Bracing, trusses, towers and connections |
| Unequal Angle | Different leg widths for special connections | Frames, brackets and structural reinforcement |
| T Section | Compact profile with one flange and one web | Supports, stiffeners and fabricated assemblies |
| Flat Bar | Simple rectangular solid section | Brackets, base components and connection parts |

Purchasing several types of steel from different suppliers can increase communication, inspection and delivery costs. ZSJH Steel can organize multiple structural profiles within one project order.
Our supply scope can cover:
Material planning based on the bill of quantities
Matching steel grades and section sizes
Procurement and production coordination
Fixed-length cutting
Drawing-based component processing
Surface-protection treatment
Component identification
Export packing
Container-loading planning
Shipping-document preparation
Hot rolled sections can be delivered as standard commercial lengths or prepared as semi-finished and finished components.
Available services include:
Sections can be cut to specified dimensions using suitable sawing, flame-cutting or CNC equipment.
Bolt holes, connection holes and installation holes can be drilled or punched according to approved fabrication drawings.
End plates, stiffeners, brackets and connection components can be welded to the main sections before shipment.
Shot blasting can be carried out to remove mill scale and prepare the steel surface for painting.
Primer, finish paint and galvanizing options are available for indoor, outdoor and industrial environments.
Each component can be marked according to its drawing number, building zone or installation sequence.
The correct profile should be selected by a qualified structural engineer. Important selection factors include:
Structural load
Beam span
Column height
Connection design
Deflection requirements
Indoor or outdoor environment
Fire-protection requirements
Corrosion exposure
Fabrication method
Transportation limitations
Applicable project standard
Direct supply from an experienced steel manufacturer
Multiple structural profiles available in one order
Support for both standard and customized specifications
Drawing-based cutting and fabrication
Material and production traceability
Strict dimensional and surface inspection
Professional export packaging
Flexible container and bulk-shipping solutions
Technical communication throughout the order
Continued support after delivery
H sections generally have wider flanges and are often selected for columns and heavy structural frames. I sections are frequently used as beams because of their efficient bending resistance. Final selection should be based on structural calculations.
