Direct supply from state-of-the-art cold roll forming facilities in Tianjin, engineered to comply with demanding ASTM, EN, and JIS steel standards.
A Decade of Excellence in Global Steel Solutions
Founded in 2010, Create (Tianjin) Material Co., Ltd. has emerged as a premier manufacturer and high-volume exporter of specialized steel products. Over the past 15 years, we have strategically positioned ourselves as a cornerstone of the international steel supply chain, combining technical manufacturing prowess with a sophisticated global logistics network.
Our operational approach is defined by uncompromising quality controls, automated cold roll-forming lines, and custom profile design capabilities. We do not merely act as an OEM; we serve as an integrated engineering partner assisting clients in material selection, structural safety optimizations, and logistics compliance.
In modern industrial civil engineering, steel structures represent the benchmark for fast, cost-effective, and highly reliable execution. As primary secondary structural components, cold-formed C purlins act as the structural bridge transferring roof loads (such as sheeting, wind, snow, and photovoltaic arrays) directly to the primary steel rafters. Standardizing their design and metallurgical attributes is vital for safety, structural integrity, and architectural longevity.
The C-shaped steel channel is profile-engineered to offer maximum strength-to-weight performance. Cold-rolled from structural steel strips, C purlins feature an outer web, two parallel flanges, and two stiffening lips. The inclusion of the stiffening lip is key to preventing local torsional buckling under load. Design engineers leverage the asymmetric properties of C-profiles for simple span and multi-span structural framing layouts, offering significant structural cost reductions over hot-rolled sections.
| Steel Grade (Standard) | Minimum Yield Strength (MPa) | Minimum Tensile Strength (MPa) | Primary Application Environment |
|---|---|---|---|
| Q235 (GB/T 700) | 235 | 370 - 500 | Standard warehouses, secondary framing, light load roofs. |
| Q355 (GB/T 1591) | 355 | 470 - 630 | High wind-load structures, heavy industrial PEBs, seismic zones. |
| S350GD / S450GD (EN 10346) | 350 / 450 | 420 / 510 | Photovoltaic framing systems, structural framing requiring high durability. |
| A653 Grade 50 (ASTM) | 340 | 450 | North American civil engineering and modular light gauge steel framing. |
Because secondary steel structural elements are often exposed to condensation, high humidity, and marine environments, selecting the appropriate surface coating is critical. Tianjin-based factories deploy dynamic coating options to meet varying site life-expectancy targets:
Unlocking procurement advantages through advanced robotic roll-forming, metallurgical control, and logistics efficiencies in China.
Our mills use CNC roll-formers equipped with inline punch arrays to ensure precise dimensioning, custom spacing tolerances (±0.5mm), and zero-waste output.
With raw material directly sourced from primary state-owned mills, we provide fully traceable Mill Test Certificates (MTC) matching EN 10204 3.1 criteria.
Located next to northern China's largest shipping gateway, our logistics operations ensure competitive freight rates, prompt customs processing, and quick turnaround times.
Steel structural profiles must align with the operational demands of the modern built environment. C Purlins, channels, and plates are designed as integral components within engineered structural systems rather than standalone components.
For large-scale warehouses, logistics depots, and factory hangars, structural engineers optimize spacing ratios using variable-thickness C purlins. Our factories support the production of C-sections up to 300mm web depth and 3.0mm thickness, allowing structures to span distances of up to 10 meters between main rigid frames. This minimizes internal column counts and maximizes usable logistics square footage.
Ground-mounted and rooftop commercial solar farms are subject to continuous wind uplift, snow accumulation, and environmental weathering. Our corrosion-resistant cold-rolled profiles, particularly when coated with Zinc-Aluminum-Magnesium alloys, provide a highly reliable alternative to expensive structural aluminum. We supply standard-profile C purlins with custom hole designs for quick mechanical fastening of solar tracker components.

We offer an expansive range of high-grade steel solutions engineered to meet the rigorous demands of modern infrastructure, automotive manufacturing, and heavy industry. Our core competencies include:
Navigating global metal purchasing requires deep process knowledge, clear communication, and transparency. As a leading exporter in northern China, Create (Tianjin) Material Co., Ltd. addresses the risks that global supply chain directors, structural engineers, and logistics managers encounter during international procurement:
Uncontrolled wall thickness and flange deviations can lead to structural assembly issues on site. By implementing automated online digital laser scanners, we measure and record dimensions in real time. This guarantees that cold-formed C and Z channels remain within design parameters, limiting structural play and easing alignment for erection teams.
Marine transit introduces structural steel to high humidity levels and salt spray, posing a rust risk for non-passivated surfaces. To address this, we use robust ocean-shipping packaging standards: heavy-duty waterproof barrier paper, steel bands, wood supports, and desiccant packs. This protection is applied to both finished C channels and coils, ensuring materials arrive free from rust and distortion.
Transparency and partnership remain the foundation of our business. To ensure total peace of mind, we invite prospective partners to verify our quality through standardized sampling and trial orders. Furthermore, we maintain an "Open Door" policy, welcoming clients to visit our Tianjin facilities for on-site inspections at any time. Our objective is the cultivation of long-term, stable, and mutually beneficial alliances that drive collective success in the global marketplace.
