How to Steel Structural Parts Production?

The production of steel structural components is a rigorous, systematic process. It typically begins with project preparation and raw material inspection, followed by layout and marking to establish dimensions. The components are then shaped through cutting, machining, assembly, and welding, and finally undergo anti-corrosion coating and factory inspection. Each stage is closely interlinked to ensure that the finished components meet design specifications and safety standards.

Η ασφάλεια και η ανθεκτικότητα των κτίρια από μεταλλικές κατασκευές depend on the manufacturing quality of each individual steel component. Any dimensional deviation or welding defect can compromise the safety of the entire structure.

Therefore, the production of steel components must strictly adhere to the building standards of the project location. Every step—from raw materials to the finished product—must be precisely controlled, with quality management integrated throughout the entire process to ensure defects are promptly eliminated.

Khome has established a rigorous quality management system; we oversee every stage of production with meticulous care to guarantee the quality of each component and ensure the safety of the entire building.

1. Επιθεώρηση εισερχόμενου υλικού

Before production begins, steel must be purchased from reputable mills. Upon arrival, it shall undergo strict inspection of chemical composition and mechanical properties (such as yield strength and tensile strength). Only materials that pass all tests are allowed to be accepted into inventory and put into use.

KHOME insists on long-term strategic cooperation with reputable steel mills. We also enforce incoming material inspection standards. These standards are even stricter than national requirements.

2. Stakeout

• Stakeout: Draw full-scale (1:1) patterns on the layout table, verify drawing dimensions and hole spacings, making templates and sample rods for cutting, bending, milling, planing, hole making, etc., for subsequent processing.

6. Steel Structure Components Assembly

The assembly of steel structural components refers to the process of joining cut steel plates, profiles, and other parts—using tack welding or connecting elements—to form integral structural members (such as H-beams, columns, and girders).

Methods include ground sampling method, copy copy assembly method, vertical assembly method, tire mold assembly method, etc.

This process is carried out on specialized assembly platforms or jigs, utilizing positioning blocks, clamps, and measuring tools to ensure the precise relative positioning of the parts. At this stage, the steel components are secured only by temporary tack welds in preparation for final welding.

After undergoing final dimensional and shape inspections, the steel components proceed to the coating stage.

Coating is not merely a simple matter of applying paint; it is a systematic protective process.

The process begins with a secondary surface cleaning of the steel components, followed by the application of an anti-rust primer.

Primers are typically zinc-rich or based on an epoxy zinc-rich system, preventing corrosion of the substrate through cathodic protection or a barrier effect. An intermediate coat increases the total coating thickness and enhances the barrier effect, while the topcoat provides weather resistance and the desired color.
