Secondary steel structure components coordinate with primary main frames to realize reliable load transmission and overall structural stability, supporting flexible building layout design. All parts are pre‑fabricated in‑factory for on‑site assembly, shortening construction cycles and cutting on‑site labor costs.
Material Options
Multiple steel grades are selectable for different project conditions. Q235B applies to general structural projects; Q355B is preferred for heavy‑load industrial scenarios. Custom steel grades and section sizes are acceptable against official engineering drawings.
Surface Protection
To prevent rust and environmental erosion, components can be processed with anti‑corrosion primer, intermediate paint, topcoat or hot‑dip galvanizing. Coating schemes can be matched for indoor, outdoor, high‑humidity or chemical‑exposed working environments.
Installation Instructions
Secondary steel structures can be installed by bolting or welding. Bolted connection enables quick assembly and convenient disassembly; welded connection achieves higher structural rigidity. Installation solutions shall be confirmed by project engineers according to actual load and site conditions.
Quality Inspection
Every production batch undergoes full checks including dimension measurement, visual appearance test, welding quality assessment, surface treatment verification and material document audit, ensuring full compliance with design specifications and industrial standards.
Packing & Delivery
Goods can be supplied in bulk binding or pallet packing depending on size and quantity. Large‑size components will be marked with project numbers and part codes for easy sorting and installation on‑site.
FAQ
Q1: Are you a manufacturer or trading company?
A: We are a professional manufacturer specializing in steel structure fabrication, metal processing and custom steel products.
Q2: Can you manufacture according to our drawings?
A: Yes. Custom production is available following your design drawings, load demands, material standards and surface‑treatment requirements.
Q3: What documents do you need for quotation?
A: Please offer engineering drawings, material grade, quantity, surface‑treatment standard, required lead time and destination port / delivery address.
Q4: Can I get samples before bulk purchase?
A: Sample supply depends on component size, material and customization degree. Standard spare parts may support samples; for tailor‑made fabricated parts, we normally provide production photos and inspection reports instead of physical samples.
Q5: How do you control product quality?
A: We implement full‑process quality management: raw‑material verification, dimension inspection, welding examination, surface assessment and final batch inspection before shipment.
Q6: What surface‑treatment options are available?
A: Main choices include anti‑corrosion primer painting, multi‑layer paint finishing and hot‑dip galvanizing. Custom coating systems are acceptable for special‑purpose projects.
Q7: What is your production lead time?
A: Lead time varies with component complexity, order volume and production schedule. We will confirm exact delivery schedule after drawings and order details are finalized.
Q8: Can these products be used for outdoor projects?
A: Yes. Outdoor application requires qualified anti‑corrosion treatment and periodic maintenance to extend service lifespan.
