D-shaped screws made of high-strength steel, which is robust and does not rust. The self-drilling D-shaped screw head has a thin thread that firmly attaches to the purlin body and is made of hardened steel. The screw tail is constructed with a regular angle and is hard so that it does not wear out when drilling. All of this contributes to the D-shaped screw's usefulness in building. This will make users feel more safe when confronted with adverse weather.
Products are made from a variety of materials, the most common of which are carbon steel and stainless steel. In accordance with the environment and usage requirements, the completed surface will be coated with an anti-corrosion coating such as Cr 3+, Cr6+, galvanized, or stainless steel. Products are made in accordance with DIN/ISO standards or to customer specifications.

From the quality of input materials , raw material preservation, through the hexagonal head stamping stage, which impacts the quality and aesthetics of the product, Cuong Thinh supplied D-shaped screws are closely regulated. Finally, the screw will move on to the step of nose shaping and thread rolling following the aforementioned procedure.
Products are sent to heat lines after going through cold processing stages, where they are heated using modern lines with preset quenching, tempering, and oil quenching temperatures and times.The product is then given the appropriate anti-corrosion layer, such as galvanized dacromet or chromium 3+/6+, if needed. To make sure that the goods on the market meet the remarkable ability of drilling and cutting materials, abrasion resistance, and corrosion resistance, all production stages are sampled and tested in compliance with laws.

Application of D- Shaped Screw
- D-shaped screws are frequently employed in the building sector, particularly when installing roofs.
- D-shaped screws, primarily used to connect the corrugated iron roof's purlin and roofing sheet. Typically, plastic grommets (also known as plastic temples) are used to close the drill holes after corrugated iron screws.
