  • Edge Treated Flat bar –
    • Edge-treated flat bars are manufactured from stainless steel plates and then processed to flatten the ends and produce a smooth finish. These stainless steel flat bars are preferred for their stonework in places where tolerance and sharpness are not that critical.
  • True stainless steel Flat bar –
    • True stainless steel bars that are likewise made via hot-rolling, annealing, and pickling tend to give a more uniform appearance from bar to bar. These bars can also be made via cold-drawn metal. Its identical surfaces on either side, together with tolerances of gradient true flat bars, makes it ideal when it comes to applications for finish, uniformity, or sharp edges.

Benefits of Stainless Steel Flats

Easy to Fabricate

Stainless steel Flat is a tough long-lasting product that can last your business for decades. It is a durable material to manage and maintain. Stainless steel tubes do not require maintenance, and due to their corrosion-resistant characteristics, they are not likely to go out of operation for years.

Strict Chemical Composition

Stainless steel contains 10.5 % of the chemical element chromium, less than 1.2 % of the structural element carbon and other alloying materials. As a result, stainless steels are corrosion-resistant and quite sturdy because of additional elements like nickel, molybdenum, titanium, niobium, and manganese.

Durability

A stainless steel that’s lightweight doesn’t buckle easily and is practically unreactive, which makes it one of the hardest substances on the market. It can handle extreme temperatures, hotness, and humidity.
