Product spotlights
Supplier highlights:This supplier mainly exports to the Democratic Republic of Congo, the UK, and Brazil. They offer full customization, design customization, and sample customization services, and have product certifications.
Moderate Strength for Structural Use: Complies with China’s GB/T 700 standard, with a minimum yield strength of 235 MPa (hence the name "Q235") and tensile strength of 375–500 MPa. This strength level is perfectly matched to non-high-load structural scenarios (e.g., building frames, equipment bases), balancing load-bearing capacity and material weight.
Excellent Toughness & Ductility: Elongation rate reaches 21–26% (varies by thickness), meaning it can withstand moderate impact, bending, or deformation without cracking. For example, it can be safely bent into arcs for architectural components or machinery casings without material brittleness.
Consistent Batch Performance: The low carbon content (typically 0.14–0.22%) ensures uniform chemical composition across batches. When sourced from stock, quality is pre-inspected (e.g., tensile tests, bending tests), avoiding performance fluctuations that risk project delays.
2. Superior Processability
Easy Weldability: All common welding methods (arc welding, MIG welding, TIG welding) are applicable. No complex pre-welding treatments (e.g., preheating) are needed for general thicknesses (≤50mm), and welded joints maintain high strength—critical for structural assembly.
Good Formability & Machinability: It can be easily cut (flame cutting, plasma cutting), drilled, punched, or rolled using conventional equipment. Even thick plates (50–200mm) can be processed into custom shapes (e.g., beveled edges for welding) without excessive tool wear.
3. Cost-Effectiveness (Enhanced by "Stock Supply")
Low Base Cost: Q235 steel uses abundant raw materials (iron ore, low-carbon alloys) and mature production processes (hot rolling), keeping the base price of plates lower than high-strength steels (e.g., Q355).
Stock Supply Saves Time & Costs: Immediate availability eliminates long production lead times (usually 2–4 weeks for custom orders) and avoids project delays. It also reduces inventory holding costs for buyers, as materials can be purchased on-demand.
4. Wide Compatibility with Secondary Treatments
Uncoated Q235 plates can be further enhanced to meet specific environmental needs:
Corrosion Protection: Accepts hot-dip galvanizing, painting, powder coating, or anti-rust oiling—essential for outdoor applications (e.g., bridge decks, outdoor equipment) to prevent oxidation and rust.
Hardness Improvement: For wear-resistant needs (e.g., machine platforms), it can undergo surface treatments like carburizing or quenching to increase localized hardness (without compromising overall toughness).
