How do you ensure quality control?

We implement 3-stage QC: 1) Incoming material inspection, 2) In-process sampling (every 500kg), 3) Pre-shipment inspection. Our defect rate is under 0.5% (industry average: 2-3%).

Which countries do you export to?

We export to 47 countries across Africa (Zimbabwe, South Africa, Kenya, Nigeria, Ghana), Middle East (UAE, Saudi Arabia), and Southeast Asia (Vietnam, Thailand). Africa accounts for 65% of our exports.

What are your most popular fastener products?

Our best-selling products are: 1) Drywall screws (3.5x25mm bugle head, fine thread) - 25% of orders, 2) Self-drilling TEK screws (#8x1/2 inch) - 20% of orders, 3) IBR roofing nails (3.05x75mm) - 18% of orders, 4) Hex bolts M10x50 Grade 8.8 - 15% of orders. We ship 50+ containers monthly to global clients.

Do you provide technical specifications and datasheets?

Yes, we provide full technical datasheets for all products including: tensile strength (MPa), yield strength (MPa), torque values, hardness (HRC), and coating thickness (μm). Datasheets comply with DIN, ISO, and ASTM standards. Request via email or WhatsApp.

Fastener Coating Systems Guide: Zinc, Galvanizing, Dacromet

Complete guide to fastener coating systems. Learn about zinc plating, hot-dip galvanizing, Dacromet, and other coatings for corrosion protection.

Zinc Electroplating

Zinc electroplating is the most common coating: Process: - Electrolytic deposition of zinc onto fastener - Typical thickness: 8-12 microns - Clear or colored passivate top coat Properties: - Good corrosion protection in mild environments - Low cost - Good appearance - Some hydrogen embrittlement risk Applications: - Indoor applications - Mild outdoor exposure - Automotive under-hood - General manufacturing TradeGo zinc plated fasteners meet ASTM F1941 specifications.

Hot-Dip Galvanizing

Hot-dip galvanizing provides excellent corrosion protection: Process: - Fasteners dipped in molten zinc (450°C) - Zinc-iron alloy layers form metallurgically bonded coating - Typical thickness: 45-85 microns Properties: - Excellent corrosion resistance (20+ years in many environments) - Complete coverage including threads - Self-healing if damaged - Thicker coating affects dimensions Applications: - Outdoor construction - Coastal environments - Infrastructure (bridges, towers) - Africa outdoor applications TradeGo hot-dip galvanized fasteners meet ISO 1461/ASTM A153 specifications.

Dacromet and Geomet Coatings

Dacromet and Geomet are advanced coatings: Dacromet: - Water-based coating with aluminum and zinc flakes - Excellent corrosion resistance - Thin coating (8-12 microns) - No hydrogen embrittlement - Salt spray resistance: 500-1000 hours Geomet: - Similar to Dacromet but without chromium - Environmentally improved formulation - Comparable performance Applications: - Automotive chassis - Infrastructure - Marine applications - High-strength bolts
