Full Hard
Hemaokang Steel (Shandong) Co., Ltd. is proud to present our Full Hard Galvanized Coil with a tensile strength of 550 MPa, precisely dimensioned at 0.8 mm x 1250 mm, specifically engineered for roll forming applications. As a manufacturer with an annual export value between US$50 Million and US$100 Million and a team of 51–100 skilled professionals, we ensure consistent quality and reliable supply. Our coil offers exceptional rigidity and dimensional stability, making it the ideal choice for demanding forming processes where strength and precision are paramount. Backed by ISO9001 certification, this product is designed to meet the needs of global markets including North America, Europe, Southeast Asia, and beyond.
Key Features & Technical Specifications
- High Tensile Strength (550 MPa): Provides superior structural integrity, reducing material thickness while maintaining load-bearing capacity — ideal for roll-formed profiles used in roofing, siding, framing, and automotive components.
- Full Hard Temper: Offers excellent spring-back control and high yield strength, ensuring consistent cross-section shapes during roll forming without excessive deformation.
- Precise Dimensions (0.8 mm x 1250 mm): Tight thickness tolerance (±0.02 mm) and consistent width (±1 mm) enable smooth feeding into roll forming machines and reduce setup time.
- Superior Galvanized Coating: Hot-dip galvanized surface with minimum zinc coating weight of Z120 (or as per request) provides excellent corrosion resistance, extending product lifespan in outdoor or humid environments.
- Excellent Formability: Despite being full hard, the material is optimized for cold bending and roll forming, with elongation ≥8% to prevent cracking or surface defects.
- Flat Surface & Edge Quality: Free from wavy edges, buckle, or coating defects, ensuring high-quality finished products.
Typical Mechanical Properties

Benefits for Your Business
- Cost Efficiency: Higher strength allows use of thinner gauge material while maintaining performance, reducing material costs per finished product.
- Reduced Downtime: Consistent dimensions and excellent flatness minimize machine adjustments and scrap during roll forming.
- Long-Lasting Performance: Galvanized coating protects against rust and corrosion, even in aggressive environments, lowering maintenance costs for end users.
- Versatile Application: Suitable for manufacturing roof panels, wall cladding, purlins, steel door frames, guardrails, and industrial shelving.

Frequently Asked Questions
-
What is the difference between full hard and soft galvanized coil?
Full hard coil has higher tensile strength and yield strength, with minimal elongation, making it ideal for structural applications that require rigidity. Soft coil is more ductile and suitable for deep drawing or bending. -
Can this coil be used for roofing panels?
Yes, it is commonly used for roll-formed roofing and siding profiles where high strength and corrosion resistance are required. -
What is the minimum order quantity (MOQ)?
Our standard MOQ is 25 metric tons per order, but we can accommodate smaller trial orders upon request. -
Do you offer custom widths or thicknesses?
Yes, we can produce coils in various thicknesses (0.3–2.0 mm) and widths (900–1500 mm) based on customer requirements. Lead time may vary. -
How is the packaging to prevent damage during shipping?
Each coil is wrapped with waterproof paper, plastic film, and steel strapping, with wooden supports for sea freight. Custom packaging is available. -
Is the zinc coating weight customizable?
Absolutely. We offer coatings from Z120 to Z275 and can also supply galvalume (Alu-Zinc) coated coils upon request. -
What certifications do you hold?
We are ISO9001:2015 certified. Our products also comply with ASTM A653, EN 10143, and JIS G3302 standards. -
Can you provide samples before bulk order?
Yes, we can send free samples (freight collect) for quality evaluation. Please contact our sales team.
