1. Introduction to zinc-aluminum-magnesium coated steel coils:  

（1）Product features:

Zinc-aluminum-magnesium coated steel coils are high-end products with high corrosion resistance, high wear resistance and excellent toughness.

（2）Alloy coating:

A dense ternary eutectic structure is formed by high-temperature solidification of zinc (Zn), aluminum (Al) and magnesium (Mg), providing effective anti-corrosion protection.

（3）Product form:

The initial form is zinc-aluminum-magnesium coils, which can be processed into steel plates and steel pipes, including square pipes and round pipes, which are very suitable for manufacturing photovoltaic brackets.

（4）Application industries:

Widely used in photovoltaic brackets, steel plate warehouses, highway guardrails, fans, material towers, automated breeding equipment, steel structure buildings, earthquake-resistant brackets, electrical cabinets, etc.

2. Process flow and production process analysis of zinc-aluminum-magnesium steel coils:

(1) Process flow:

including surface treatment, coating, curing and testing.

Surface treatment: cleaning, degreasing, pickling, etc. to ensure the adhesion between the coating and the substrate and the surface flatness.

Coating: The zinc-aluminum-magnesium alloy coating is evenly coated on the surface of the coil by rolling coating, spraying, etc.

Curing: Drying and heating at 110℃-150℃ to ensure the firmness and durability of the coating.

Inspection: Conduct quality inspection and performance test on the coated coil to ensure that the product meets the requirements.

(2) Production process:

including raw material preparation, surface treatment, forming processing, quality inspection, packaging and transportation, storage and custody, safety and environmental protection measures and quality control and inspection.

Raw material preparation: Select steel coils and zinc-aluminum-magnesium alloys that meet the requirements.

Forming processing: straightening, shearing, forming, etc.

Quality inspection: appearance inspection, size inspection, mechanical property inspection.

Packaging and transportation: Use protective film, cartons and other materials for packaging to prevent damage during transportation.

Storage and custody: Store in a dry, ventilated and pollution-free environment.

Safety and environmental protection measures: Pay attention to safety operating procedures and use environmentally friendly materials and methods.

Quality control and inspection: Establish a complete quality control system and conduct sampling inspection on products.
