GL (Galvanized-related Products) Product Details

Superior Quality, the Preferred Choice for Protection

Our GL series products feature advanced galvanizing processes at their core. Through hot-dip galvanizing or electro-galvanizing techniques, a dense zinc layer protective film is formed on the metal surface. This zinc layer not only effectively resists oxidation, acid and alkali corrosion but also significantly enhances the product's abrasion and impact resistance, extending its service life to 3 to 5 times that of ordinary metal products. They are widely applicable in harsh environments such as construction, transportation, and machinery manufacturing.

Diverse Processes, Precise Customization

We offer two process options: hot-dip galvanizing and electro-galvanizing. Hot-dip galvanized products can have a zinc layer thickness of up to 80 - 120μm, providing excellent weather resistance and are suitable for long-term outdoor use. Electro-galvanized products are renowned for their fine and uniform coating and smooth, attractive surface, making them ideal for applications with high aesthetic requirements, such as home appliances and furniture. Additionally, we support customization of zinc layer thickness, product specifications, and surface treatments (such as passivation and oil coating) to meet diverse needs.

Rigorous Quality Inspection, Quality Assurance

The entire production process adheres to the ISO 9001 quality management system. From raw material screening to finished product delivery, the products undergo more than 10 inspection procedures. Each batch of products passes salt spray tests, adhesion tests, and mechanical property tests to ensure strong zinc layer adhesion, no missing plating, and no bubbles. The quality meets domestic and international standards such as ASTM and GB.

Considerate Services, Win-Win Cooperation

We support small-batch trial orders and large-scale customized production. Regular orders can be delivered within 3 - 7 days, and we provide one-stop services for logistics tracking and customs clearance. Our professional technical team can assist in optimizing product designs, offer installation and maintenance guidance, and respond to after-sales inquiries within 24 hours, ensuring a worry-free procurement experience for you.

• Q1: What is the difference between hot-dip galvanized and electro-galvanized products in your GL series?
  A1: Hot-dip galvanized products in our GL series feature a thick zinc layer (80 - 120μm), providing superior corrosion resistance and durability, making them ideal for outdoor applications like construction and bridge components. Electro-galvanized products, on the other hand, offer a thinner, more uniform coating with a smoother surface finish, suitable for indoor uses such as home appliance casings and furniture where appearance matters.
• Q2: Can I customize the zinc layer thickness for GL products? What's the minimum order quantity?
  A2: Yes, we fully support customizing the zinc layer thickness according to your project requirements. The minimum order quantity varies based on the process and specifications, typically starting from 1 ton for standard products. For customized orders, our sales team will provide a detailed quote after assessing your needs.
• Q3: How do you ensure the quality of GL products? What certifications do they have?
  A3: All GL products undergo strict quality control, including 10+ inspection processes like salt spray tests, adhesion tests, and mechanical property assessments. They comply with international standards such as ASTM and domestic GB regulations, and are certified by ISO 9001. We can also provide SGS test reports upon request.
• Q4: What is the delivery time for GL products? Do you offer international shipping?
  A4: For regular orders, the delivery time is 3 - 7 days. Customized orders may take 10 - 15 days depending on complexity. We provide international shipping services and offer one-stop logistics solutions, including customs clearance assistance to ensure smooth delivery to your destination.
