Â
Stainless steel is a steel alloy with a minimum of 10.5% chromium content, as well as certain Ni, Mo, Mn, Cu, N contents etc.
Stainless steel does not readily corrode, rust or stain with water. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and corrosion resistance are required.
Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion and blocks corrosion from spreading into the metal.
Â
Physical and chemical properties:
High oxidation resistance in air at ambient temperature;
Highly resistant to attack from acids, bases, organics;
High resistance to stress corrosion cracking;
High resistance to general corrosion, pitting corrosion, crevice corrosion, erosion corrosion and corrosion fatigue;
High mechanical strength.

  We will reply you in Island Light
Island Light is a type of Pendant Light commonly used over the central island in a kitchen or over a long table in a dining room. It typically has multiple bulbs to provide sufficient light to illuminate the entire area. Island Lights come in a wide variety of designs, ranging from traditional pendant styles to modern, industrial, or artistic designs. Island Lights not only provide light but can also serve as a decorative element in a room.
Chandelier Light is a commonly used lighting decoration on the island of a restaurant, which can not only meet the lighting function, but also serve as the main focal point decoration of the restaurant. The Island Light is made of a variety of materials, such as crystal, glass, metal, etc., and has a variety of design styles, which can be matched according to your preferences and the overall style of the restaurant. As a rule of thumb, a gap of 72 cm to 90 cm between the edge of the Lighting Fixture and the surface of the island is optimal. Small islands (1.2 to 1.5 m long) are usually suitable for two medium-sized Island Light or a large Island Light. As for the larger islands, three medium-sized or two larger Island Light can be handled.
