Handan Jinmai Fastener Manufacturing Co., Ltd. (hereinafter referred to as "Handan Jinmai Fastener Manufacturing Co., Ltd.") specializes in the production of high-performance angle iron, specifically designed for power fittings, fiber optic cable line accessories, and iron accessory systems. As a source manufacturer, we offer a full range of custom hot-dip galvanized angle iron, including equal/unequal-legged, perforated, and slotted configurations, meeting the rigid support requirements of power towers, cable trays, and iron accessory connections. Our products strictly adhere to ASTM/AISI international standards (hereinafter referred to as "ASTM") and are suitable for demanding environments such as high-voltage transmission and transformation projects and communication base stations.
1. The power-specific design optimizes structural mechanical performance, achieving a support capacity that meets 500kV ultra-high voltage (UHV) standards (referring to the high-voltage scenario of Gulifa Group), effectively withstanding strong winds, icing, and other loads.
2. Long-lasting weathering and corrosion resistance is achieved through hot-dip galvanizing (zinc layer ≥ 80μm), ISO 1461 certified (), with a salt spray corrosion life exceeding 30 years, making it suitable for coastal and industrially polluted environments.
3. Flexible customization supports non-standard dimensions:
Equal-leg angles: 20×20×3mm to 200×200×20mm
Unequal-leg angles: 25×16×3mm to 200×125×14mm
Lengths: 1-12m (can be cut to any length)
4. Q235B/Q345B carbon steel is used for a balance of strength and lightweight, achieving a tensile strength of 510MPa and a 15% weight reduction compared to traditional angle steel, reducing the overall tower cost.
1. Precision forming using fully automated CNC wire cutting and cold bending technology (referring to Shandong Haihong's technology), with an angle tolerance of ≤0.5°, ensuring assembly compatibility.
2. Enhanced surface treatment with a triple-layer protection process: pickling and rust removal → hot-dip galvanizing → passivation and sealing. Passed the corrosion protection test of the National Electric Power Hardware Quality Testing Center ().
3. Strict quality control system: Mechanical property testing (tensile and bending tests) and full dimensional inspection are performed on each batch, complying with GB/T 706-2016 standards .
