OEM Overview:
We are a professional steel structure solutions provider specializing in fully customized services, offering tailor-made steel structure building products to meet diverse project requirements.
Our customization process typically follows two flexible scenarios, ensuring a seamless experience for clients with or without pre-designed plans:
Scenario 1: Client Provides Design Drawings
When clients submit complete design drawings, our technical team conducts a comprehensive review and prepares a detailed, accurate budget based on the specifications, material requirements, and project scope outlined in the documents.
Scenario 2: Client Has Conceptual Ideas (No Drawings)
For clients with conceptual needs but no formal drawings, our experienced design team translates ideas into professional schematic diagrams. We collaborate closely with clients to refine the design—incorporating adjustments to dimensions, functions, or aesthetics—until full approval is obtained. Following design confirmation, we finalize the project budget.
Subsequent Project Phases
Construction Drawing Development: Post-budget approval, our engineering team creates detailed construction drawings (including fabrication and erection details) that adhere to international standards (e.g., EN 1090, AWS D1.1, GB/T 50205).
Client Confirmation: The construction drawings are submitted to the client for final review and sign-off to ensure alignment with their expectations.
Pre-Production Preparation:
Our technical department breaks down the construction drawings into shop drawings (detailed fabrication guides for each component).
We source high-quality raw materials (e.g., Q355B, S355JR, 304 stainless steel) from certified suppliers to guarantee product performance.
Factory Fabrication: The workshop executes production strictly in accordance with the shop drawings, leveraging advanced equipment (CNC cutting machines, automatic welding systems, shot blasting machines) to ensure precision and quality.
Packaging & Shipping Readiness: Finished components undergo professional packaging (weather-resistant, anti-corrosion wrapping with labeling for easy assembly) and are prepared for shipment as scheduled.
Throughout the entire process, we maintain open communication with clients, providing real-time updates on design progress, production status, and logistics arrangements. Our goal is to deliver turnkey customized steel structure solutions that combine technical excellence, cost-effectiveness, and on-time delivery.
