Longyi Import and Export specializes in hot-dip galvanized steel coils, PPGI color coated steel coils, and aluminum zinc coated steel strips, which are performance compatible with four core industries. They cover the global procurement needs of the entire industry chain of construction engineering, household appliances, transportation, and agricultural equipment, providing one-stop supply of various anti-corrosion steel substrates and solving multi category procurement problems.

The first major field: the construction industry, which is also the largest application scenario for coated steel coils. Hot dip galvanized steel coils can be used to process corrugated roof tiles, wall cladding panels, C/Z-shaped steel purlins, ventilation ducts, cable trays, and light steel villa keels; PPGI color coated rolls are commonly used for factory exterior walls, roofs, sandwich panels, door and window decorations, and outdoor enclosures. For large industrial parks, prefabricated support buildings, and logistics warehouses, the combination of galvanizing and color coating can significantly reduce the investment in rust prevention and maintenance in the later stage, and the service life can reach more than 10 years. A large number of overseas infrastructure projects use Longyi steel, which has the advantage of having a complete range of specifications, including color coated tiles as thin as 0.14mm and structural galvanized sheets as thick as 2.5mm, suitable for different sizes of construction projects.

The second major field: home appliance manufacturing. The casings of refrigerators, washing machines, air conditioners, range hoods, and water heaters are all made of fingerprint free hot-dip galvanized steel coils. The deep drawing grade substrate is bent and formed without cracks, and the surface passivation and oil coating process is not easy to leave fingerprints, improving the appearance and texture of household appliances. We specialize in deep drawing DX51D and SGCD galvanized coils for European and American standards, with high dimensional accuracy and environmentally friendly coatings that meet import environmental testing requirements for European and American home appliance companies. We also provide long-term supply to home appliance factories in Southeast Asia and the Middle East.

The third major field: transportation industry. Highway waveform guardrails, car chassis protective panels, interior and exterior decorative panels, container side panels, and bus interior panels are all made of coated steel. The highway guardrail uses thickened zinc coated galvanized steel coils to resist outdoor rainwater and snow melting agent corrosion; The interior and cabin decoration of the car are made of PPGI color coated rolls, which are rich in color, lightweight and easy to process; The container substrate is made of high-strength galvanized substrate, which balances load-bearing and rust prevention performance. Longyi high-strength S350GD and CGC570 high-strength steel grades are suitable for the load-bearing requirements of transportation structural components.
The fourth major field: agricultural machinery and storage facilities. Agricultural grain storage steel silos, greenhouse skeletons, breeding fences, and irrigation equipment casings all rely on galvanized steel. In rural environments with high humidity and soil corrosiveness, ordinary steel is prone to rusting, and hot-dip galvanized layers can achieve long-term protection. We have launched a large zinc layer 180g/㎡ galvanized steel strip specifically for agricultural projects, which is resistant to soil and water vapor corrosion. The single warehouse service life can reach more than 10 years and is highly recognized by agricultural equipment manufacturers in Africa and Southeast Asia.

In addition, the product can also be used in segmented scenarios such as small hardware processing, solar brackets, and pipeline anti-corrosion outsourcing. Longyi can recommend steel solutions that match the thickness, zinc layer, coating, and material grade according to the customer's industry, to avoid cost waste caused by blind procurement by customers. At the same time, it supports the processing of various types of steel strips and plates by slitting and flattening, and comes with complete inspection documents for shipment. It is compatible with import standards of various industries. Overseas buyers from various industries are welcome to consult and customize steel solutions.
