High-Strength Steel Plates--S690QL+Z25 & Q690D

We keep two types of high-quality high-strength structural steel plates in stock, with complete specifications, precise dimensions, genuine materials and controllable quality. They are suitable for harsh working conditions in heavy engineering, high-end equipment manufacturing and other fields, can meet project needs under various high-load and complex environments, and support on-demand processing and full-process quality traceability.

Type 1: S690QL+Z25 High-Strength Steel Plate

Core Specification: 30*2000*7300mm (thickness 30mm, width 2000mm, length 7300mm). The material complies with EN 10025-6 standard, belonging to high-strength structural steel, with excellent mechanical properties and process performance. Among them, Z25 grade lamellar tearing resistance effectively avoids interlayer cracking during thick plate welding, especially suitable for heavy-duty structural scenarios with dense welding and complex forces.

Material Advantages: Tensile strength is over 690MPa, yield strength is stable, toughness is excellent, impact resistance and fatigue resistance are good, and it can bear high load; the surface is flat, dimensional error strictly follows national standards, no pores, cracks and other defects, good processing performance, and can smoothly complete subsequent processing procedures such as cutting, welding and bending.

Applicable Scenarios: Heavy engineering machinery (such as cranes, excavators, loaders), large steel structure workshops, bridge structures, offshore platforms, high-end equipment frames and other fields with high requirements for steel strength and welding performance.

Type 2: Q690D High-Strength Steel Plate

Core Specification: 10*2500*12000mm (thickness 10mm, width 2500mm, length 12000mm). The material complies with GB/T 1591 standard, belonging to low-alloy high-strength structural steel, with outstanding low-temperature toughness, can adapt to low-temperature working environment, and stable and reliable performance.

Material Advantages: Yield strength ≥690MPa, tensile strength up to standard, excellent low-temperature impact toughness (qualified impact at -20℃), corrosion resistance and wear resistance, uniform material, smooth surface, precise dimensions, can be directly put into processing without additional treatment, effectively improving project construction efficiency.

Applicable Scenarios: Various medium and heavy structural parts, engineering machinery parts, equipment casings, building steel structures, mining machinery, vehicle manufacturing and other fields, especially suitable for outdoor projects and equipment used in low-temperature environments.

Quality Assurance: Both types of steel plates are from regular steel mills. Each batch of goods is equipped with a complete material certificate, supporting full-process traceability. Every link from raw material procurement, production inspection to delivery can be verified to ensure genuine materials and correct specifications. We strictly implement multiple quality inspection processes to eliminate defective products from leaving the factory. At the same time, we support supporting processing services such as on-demand cutting, beveling and flaw detection. The stock is sufficient, available for same-day pickup, meeting project procurement needs in one stop.
