Cold formed steel sections provide an efficient solution for projects requiring high structural performance, reduced weight and accurate factory-made components.
ZSJH Steel produces standard and customized profiles from quality-controlled steel coils. Through precision roll forming, punching and cut-to-length processing, we manufacture ready-to-install steel sections for roofing systems, wall support systems, modular buildings, light steel framing, solar structures and industrial applications.
Customers can order standard C, U and Z sections or submit drawings for specially designed profiles with customized folds, stiffening ribs, holes, slots and protective coatings.

C and Z sections support roofing sheets and transfer roof loads to the primary steel frame. Z sections can be overlapped at supports for continuous-span construction.
Cold formed channels provide secondary support for wall cladding, insulation systems and exterior panels in industrial buildings.
C studs, U tracks and custom profiles can be used for walls, floors, roofs and supporting frames in light gauge construction.
Accurate dimensions and standardized connection holes make cold formed profiles suitable for repeatable factory production and rapid on-site assembly.
Galvanized C channels, slotted profiles and custom mounting sections can be supplied for rooftop and ground-mounted solar systems.
Perforated upright profiles and reinforced cross members are suitable for warehouse shelving and industrial storage systems.
Hat channels, omega profiles and furring channels support façade panels, ceilings, partitions and decorative wall systems.
Customized profiles can be produced for equipment enclosures, machinery supports, conveyor systems, doors, windows and other industrial products.
For special projects, our team evaluates the complete section design before production.
The customization process includes:
Reviewing the profile drawing or sample
Confirming material grade and thickness
Checking bending radii and section geometry
Evaluating roll-forming feasibility
Confirming holes, slots and tolerances
Developing production tooling when required
Producing and inspecting trial samples
Confirming the sample before batch production

Yes. Please send the section drawing, steel thickness, required length and estimated quantity. We will evaluate tooling and production feasibility before quotation.
C sections are commonly used for simple-span systems, while Z sections can be overlapped at supports for continuous-span arrangements. The final selection should follow the structural design.
Yes. Holes and slots can be punched during production according to the approved drawing.
Yes. Pre-galvanized materials and other corrosion-protection options can be supplied based on the required project environment.
Yes. Required tolerances should be indicated on the drawings and confirmed during the technical review before production.
