What‘s The Feature Of Stainless Steel Profiles?

Stainless steel profiles come in various shapes and designs to suit different applications. Each profile has a specific cross-sectional shape, such as L-shaped (angle), U-shaped (channel), I-shaped (I-beam), cylindrical (round bar), or specific custom designs.

Stainless steel profiles offer excellent structural strength, making them suitable for applications where support and load-bearing capabilities are required. They can withstand heavy loads and provide stability in construction and structural projects.

Like other stainless steel products, stainless steel profiles offer excellent corrosion resistance. They are resistant to rust, staining, and oxidation, ensuring durability and longevity in both indoor and outdoor environments, even in corrosive conditions.

What Services Does Gnee Provide?

Gnee can provide the following measurement services for stainless steel:

Dimensional Measurement: Measure dimensional parameters such as length, width and thickness by measuring instruments to ensure that the stainless steel is qualified and meets the design requirements.
Surface Measurement: Measure parameters such as flatness, bumpiness and surface roughness of the stainless steel surface to help ensure that the quality and surface condition of the stainless steel meets the requirements.
Thickness Measurement: Use thickness gauges to accurately measure the thickness of the stainless steel to ensure it meets the design requirements.
Material Measurement: Use material analysis instruments to measure the chemical composition and mechanical properties of the stainless steel to ensure that the quality and properties of the stainless steel meet the requirements.
