BLOG – Why using SUS304 Stainless steel for solar mounting solutions?

In the solar energy sector, stainless steel is a widely used material. The material SUS304 is  steel is renowned for its strength, durability, and corrosion resistance. Among its variants, SUS304 stands out as a particularly popular choice across various industries, including solar energy. But what sets SUS304 apart, and why is it so favored?

Understanding SUS304

SUS304 is the Japanese designation for 304 stainless steel, an alloy primarily made up of iron, with 18% chromium (Cr) and 8% nickel (Ni). This composition ensures excellent corrosion resistance and workability, making it the most widely used stainless steel alloy globally.

Key Benefits of SUS304

Corrosion Resistance: SUS304’s high chromium content creates a protective layer on the surface, shielding the metal underneath from rust and other forms of corrosion. This makes the type of material ideal for solar installation material.

Durability: Known for its longevity even under harsh conditions, SUS304 is a cost-effective choice for projects where long-term durability is essential.

Versatility: Its excellent workability allows SUS304 to be shaped, welded, and finished to meet specific requirements. Do you need adapted installation material for installing solar panels?
