Steel Structure Material Processing | Custom Cutting, Punching, Welding and Anti-corrosion One-stop Deep Processing Service
1. Processing Overview
We are a professional steel structure manufacturing and processing factory equipped with full sets of advanced production equipment, including CNC precision cutting machines, automatic submerged arc welding systems and integrated shot blasting production lines. We deliver one-stop customized processing and factory prefabrication services for H-beams, C-beams, channel steel, steel plates and all conventional steel profiles. These processed steel components are widely used as supporting frames for Color Steel Rock Wool Sandwich Panel and Color Steel Polyurethane Sandwich Panel.
Supported by full CNC precision machining and standardized factory prefabrication, we provide professional drawing deepening and non-standard component customization. Replacing traditional messy on-site processing, our integrated factory production effectively improves component precision, shortens overall construction cycles and reduces project labor and comprehensive costs. We process conventional Q235B and Q355B carbon steel, as well as special engineering materials including Q355NL low-temperature impact-resistant steel (-40℃), Q355GNH weathering steel and multiple stainless steel grades, fully adapting to complex and diverse engineering operating conditions.
2. Core Processing Items & Technical Standards
Precision Fixed-length Cutting Adopting CNC sawing and plasma cutting integrated technology for standard sizing and non-standard custom blanking. The cutting length tolerance is strictly controlled within ≤±1.0mm, with flat and burr-free end faces. It meets the high-precision sizing requirements of various steel structural components for assembly projects.
Multi-specification Precision Punching Custom fabrication of round holes, slotted holes and special-shaped holes compatible with international bolt standards. All mounting and connecting holes are prefabricated in the factory, with positional tolerance controlled within ≤±0.5mm. Components can be directly installed via bolt connection on site without secondary drilling or modification, ensuring perfect assembly accuracy.
Bending, Leveling & Deformation Straightening Professional mechanical correction and straightening processes eliminate side bending, twisting and structural deformation caused by processing. Custom special bending forming is supported to guarantee component flatness, straightness and overall uniformity, fully meeting project acceptance specifications.
High-standard Structural Welding We adopt automatic SAW submerged arc welding and GMAW gas metal arc welding for structural splicing. Weld seams are uniform, smooth and free of pores and slag inclusions. Complying with GB/T 11345 and AWS D1.1 international welding standards, we provide Grade I and Grade II UT non-destructive testing services, applicable for heavy-load, high-rise and key structural engineering projects.
Multi-grade Custom Anti-corrosion Treatment We provide diversified anti-corrosion solutions covering Sa2.5 grade shot blasting, hot-dip galvanizing, AZ150 aluzinc coating and composite paint finishing. Conventional hot-dip galvanizing achieves a coating weight ≥180g/㎡, while heavy-duty galvanizing reaches ≥275g/㎡ for C5-M coastal high salt-spray corrosive environments. The epoxy zinc-rich primer plus topcoat system delivers a total dry film thickness ≥80μm (customizable), adapting to indoor dry, outdoor exposed and heavy industrial corrosive working conditions.
3. Core Processing Advantages
High-efficiency Factory Prefabrication All core processing procedures are completed in the factory with standardized assembly. It eliminates tedious secondary on-site processing, greatly accelerates construction progress and effectively reduces on-site labor costs and construction risks.
Strict Precision & Stable Tolerance Control Full-process CNC intelligent machining ensures consistent dimensional accuracy and excellent component interchangeability. All parts match modular prefabricated construction systems perfectly, avoiding assembly errors caused by manual on-site processing.
Complete One-stop Service Integrating drawing deepening, precision cutting, forming bending, structural welding, anti-corrosion treatment and finished product packaging, we realize one-stop procurement and one-time delivery, simplifying customer cooperation and project management procedures.
Powerful Non-standard Customization Capacity We support customized production of non-standard sizes, special-shaped structures and variable cross-section components, flexibly responding to personalized structural design requirements of complex industrial, municipal and new energy projects.
Full-process Quality Traceability Standardized full-process quality inspection and sampling testing are implemented throughout production. Complete qualification documents are provided, supporting third-party institutional testing and meeting domestic and international project acceptance standards.
4. Application Scenarios
Industrial Steel Buildings: Prefabricated steel frames, secondary purlins and enclosure supporting components for factory workshops, warehouses and light steel industrial buildings.
New Energy PV Projects: Custom prefabricated steel structural components for rooftop photovoltaic brackets and ground-mounted solar power station support systems.
Municipal Auxiliary Facilities: Structural steel parts for outdoor canopies, carports, pedestrian corridors, viewing platforms and municipal landscape structures.
Special Engineering Projects: Custom equipment support frames, bridge auxiliary components, trestle steel structures and corrosion-resistant steel parts for chemical plants.
5. Delivery, Packaging & Comprehensive Service
Standard cutting and punching orders are delivered within 2–5 working days. Custom welded components and heavy-duty anti-corrosion processed products take 7–12 working days, with flexible expedited production available for urgent orders.
Finished steel products are tightly bundled and fixed with wooden skids to prevent deformation. For export orders, we adopt fumigated wooden pallets, rainproof protective films and high-strength steel strapping, fully adapting to container loading and long-distance sea transportation.
We provide professional DWG/PDF drawing deepening optimization, full-process quality inspection reports and complete sets of acceptance documents to support global project approval.
6. FAQ
Q1: Can you process customized steel components according to construction drawings? A1: Yes. We support full drawing-based customized production. All non-standard sizes, special-shaped structures and special hole spacing components can be precisely processed to fully match customer design drawings and engineering requirements.
Q2: Can processing accuracy and tolerance standards be guaranteed? A2: Adopting full CNC precision machining technology, our standard tolerance is controlled within ≤±1.0mm. High-precision tolerance up to ±0.5mm is available for high-standard projects, with zero structural deformation and stable assembly performance.
Q3: What anti-corrosion solution is suitable for outdoor and coastal projects? A3: Standard hot-dip galvanizing is applicable for conventional outdoor environments. For coastal salt-spray and heavy industrial high-corrosion areas, heavy-duty thick galvanizing or AZ150 aluzinc coating is highly recommended to extend the structural service life significantly.
Q4: Can you provide complete documents for project acceptance? A4: We supply full sets of official documents, including mill test certificates, welding UT non-destructive inspection reports and anti-corrosion coating test reports. All products support SGS third-party testing and meet global engineering acceptance standards.
