Steel frames, concrete reinforcement, roofing and cladding.
Overview
Commercial, industrial and residential buildings use steel in three main ways: frames, reinforcement for concrete, and the envelope. A single project may need H-beams and plate for the frame, rebar for the cores and slabs, and coated coil for the roof and walls.
Because several trades buy steel for the same building, combining their requirements early can simplify inspection and logistics. Seismic zones, fire protection and the local climate all affect what should be specified.
Where each steel product is used
| Structure | Steel product | Typical grades / standards |
|---|---|---|
| Columns, beams and frames | H-beam | Q355B / S355JR / A992 |
| Slabs, cores and foundations | Rebar | HRB400E / HRB500E, GB/T 1499.2 |
| Stirrups and smaller reinforcement | Rebar coil | HRB400E, GB/T 1499.2 |
| Roofing and wall cladding | Pre-painted coil | DX51D + Z / AZ, PE / SMP / PVDF |
Grades shown are typical examples. The project's design documents and applicable codes decide the final specification.
Common standards: GB/T 11263, GB/T 1499.2, EN 10169
What the project needs
- H-beams and columns for steel frames
- Rebar and coiled rebar for concrete
- Pre-painted and Galvalume coil for envelopes
What to consider when selecting steel
Seismic requirements
Seismic-grade rebar such as HRB400E and structural steel with controlled yield properties may be needed. Check the requirements of the local code.
Envelope coating
Base coating and paint system, such as PE, SMP or PVDF, should match the climate and the expected colour life of the building.
Coordinated delivery
Frames, rebar and cladding arrive at different stages. Packing lists and marking by building zone make site handling easier.
Recommended products
What to include in your inquiry
- Steel schedule by section, grade and length
- Rebar diameter, grade and tonnage by size
- Coil base metal, thickness, coating and paint colour
- Local code requirements and required certificates
Frequently asked questions
What does the E in HRB400E mean?
It indicates seismic-grade rebar, with additional requirements on properties such as yield ratio and elongation under GB/T 1499.2.
Which paint system should be used for cladding?
PE is common for general use, SMP offers better durability, and PVDF is often chosen for higher colour retention. The climate and budget decide.
Can different products ship together?
Mixed shipments can be discussed. Sections, rebar and coil load differently, so the plan depends on sizes, port and vessel type.
