How to measure the thickness of patterned steel plate?
Patterned steel plate is widely used for its anti-slip properties and structural strength. Its thickness measurement requires a balance of accuracy and operational standards. Unlike ordinary steel plate, the uneven pattern design of patterned plate imposes special requirements on measurement methods.

The key to measurement is distinguishing between "nominal thickness" (including pattern height) and "actual substrate thickness," the latter of which directly determines the material's load-bearing capacity. The "three-zone sampling method" should be used for measurement. Three to five flat, pattern-free areas are selected at the edge, center, and diagonal locations of the steel plate to establish a three-dimensional inspection network.

Pretreatment of the sampling points requires cleaning with alcohol to remove the oxide layer. Severely corroded areas should be sanded to a metallic sheen. Multi-dimensional measurement requires measuring each sampling point once at 0°, 90°, and 45°. The data is recorded, and the average value is calculated for that point. This cross-sectional measurement method effectively identifies localized substrate unevenness.
What is the difference between a lentil pattern and a diamond pattern on patterned plate?
The anti-skid property, load-bearing capacity and decorative effect of the concave-convex patterned plate are closely related to its pattern shape.

Patterned lentil plate is a machine-processed building material that offers high strength and corrosion resistance. It is commonly used for roofing and wall decoration. Its surface features a linear texture that provides excellent anti-slip properties and enhances its aesthetic appeal.

A diamond pattern is created by cold-pressing the surface of a steel plate, resulting in a regular diamond pattern. This pattern is both aesthetically pleasing and offers a degree of anti-slip properties, making it commonly used in areas requiring anti-slip protection, such as vehicles and factory floors.
What are the properties of 304 stainless steel finned heat pipes?
304 stainless steel is a general-purpose stainless steel containing 18% chromium and 8% nickel, offering excellent corrosion resistance and mechanical strength. 304 stainless steel maintains excellent stability in high-temperature environments and is not easily oxidized or deformed, making it an ideal material for heat pipes. Compared to ordinary carbon steel, 304 stainless steel performs better in humid or corrosive environments, significantly extending the service life of heat pipes. 304 stainless steel also has excellent thermal conductivity, with a coefficient of approximately 16.3 W/(m·K), effectively transferring heat from the heat source to the heat dissipation surface.

The primary function of fins is to increase the heat dissipation surface area and improve heat exchange efficiency. Common fin types include spiral fins, longitudinal fins, and annular fins.
