A carbon steel-based mechanical fixing device engineered for permanent installation in solid masonry materials (concrete, stone, etc.), which achieves a tight grip by means of a wedge mechanism that expands against the hole wall when the anchor’s external nut is torqued down. Carbon Steel Wedge Anchor Bolt can be used for normal weight concrete, lightweight concrete and solid masonry. Sometimes called wedge bolts, wedge anchors operate on an expansion principle. They are installed into a pre-drilled hole, and as the nut is tightened to the specified torque, the wedge expands and secures the anchor into the concrete.

A ring groove rivet is a high-strength fastening connector consisting of two parts: a rivet shank and a collar. The surface of the rivet shank is equipped with annular grooves, and the collar is sleeved on the grooved section of the rivet shank. Size Diameter (length) M16, M20, M24, M28, M32, M36, M44 Material 20MnTiB  Application This connection method features strong vibration resistance, high shear resistance, and no risk of loosening after installation. Working Principle During installation, a special tool applies axial pressure to the collar, causing it to undergo plastic deformation and tightly embed into the ring grooves of the rivet shank, forming a firm mechanical locking structure.This connection method features strong vibration resistance, high shear resistance, and no risk of loosening after installation.

Torque-shear bolt is also well known for torsional shear bolt, is a specialized high-strength fastener designed for critical structural connections. Its external feature is that the bolt head is cup head, and at the end of the rod, there is a plum blossom-shaped "breaking groove" (i.e., the torque control section), which is used in conjunction with the matching torque- shear type nuts and washers.

Carbon steel is an alloy of iron and carbon, typically containing up to 2% carbon, along with varying amounts of other elements such as manganese, silicon, and sulfur. It is one of the most widely used types of wire mesh due to its excellent strength, affordability, and versatility. Carbon steel wire mesh is typically available in plain weave, twill weave, and various other weaving patterns, and can be manufactured in different mesh sizes, wire diameters, and forms such as rolls, sheets, or panels. Carbon steel wire mesh has a characteristic dark or blackish metallic appearance, and it can be finished with coatings such as galvanization, PVC, or paint to enhance its resistance to corrosion and extend its lifespan. Without protective coatings, carbon steel is prone to rusting, especially when exposed to moisture or corrosive environments. Properties: Generally, the higher the carbon content of carbon steel, the greater the hardness and the strength, but the lower the plasticity. Carbon steel wire cloth is known for its strength and durability, making it suitable for heavy- duty applications. While carbon steel is susceptible to corrosion, it can be protected with coatings. It is generally more economical compared to stainless steel and other specialty alloys. 

Hexagonal wire mesh, also known as chicken wire or gabion box, is a versatile type of wire mesh characterized by its hexagonal pattern. It is typically made from low-carbon steel wire, galvanized steel wire, or stainless steel wire, and sometimes PVC-coated for additional corrosion resistance and aesthetic appeal. The mesh size is typically ranges from 1/2 inch to 4 inches, with wire diameter that ranges from 0.5 mm to 2 mm, depending on the application requirements. The weaving type of it is divided to Normal twist and Reverse twist. Properties The hexagonal pattern is flexible, making it easy to bend, cut, and shape to fit various applications. Compared to other types of wire mesh, hexagonal mesh is relatively lightweight, which facilitates easy handling and installation. In addition, depending on the material and coating, it offers good durability and resistance to weathering, especially when galvanized or PVC-coated. Generally cost-effective, especially when made from galvanized steel, making it an economical choice for large-scale fencing and enclosure projects.

The warp and weft of the reverse dutch weave mesh forms a horizontal triangular opening. The significant difference between reverse Dutch weaving and Dutch weaving lies in the more warp yarn and fewer weft yarns, making the woven mesh more robust and stable. Through the continuously technological innovation and improvement, we can produce various specifications of reverse Dutch woven stainless steel wire mesh. Additionally, we are the pioneer of research and develop reversed dutch weave wire mesh, who hold two patents, which namely, plain weave reversed mesh and twill weave reversed mesh. The much more experience in weaving reversed dutch weave wire mesh makes us very handy and confident, which also obtains the customer trust and support.  

The most classic and commonly used weaving type with relatively lower cost Square weave wire cloth is made by weaving wires together and formed as a square aperture, typically using stainless steel 304(L), 316(L), 321,310s, it also can be made of other materials, such as brass, copper, bronze,or aluminum etc.. It is a versatile material used in various industrial filtration, sieving, protection, and separation purposes. Plain Weave Plain weave is the most popular and commonly used weave type. The warp wire cross the weft wire in turn. The warp wire, which also called shut wire, has nearly same diameter as the weft wire. Twill Weave Each weft wire traverses alternatively over two, then under two consecutive warp wires, while each warp wire alternates over two and under two consecutive weft wires. This weave technique permits the accommodation of a wire diameter heavier than the standard.

Stainless Steel Ultra-thin Wire Mesh is a kind of wire mesh which made from exceptionally thin wires, often with diameters measured in microns. The uses of carefully selected materials and the most advanced weaving technology adopted ensure the thickness of the wire mesh is within the allowed tolerance range. Hence the precision of the wire mesh is further enhanced for printing requirements. Ultra-thin wire mesh is famous with its combination of precision, flexibility, and strength. The mainly applications of it are in advanced industrial, medical, and scientific applications. Woven wire cloth ability to perform in demanding environments where both fine detail and high performance are required sets it apart from other types of wire mesh. Properties: Ultra-thin stainless steel wire cloth is used typically when heat and corrosion resistance is required, and frequently utilized in applications requiring shielding of electromagnetic interference and radio frequency interference. All of Ultra-thin wire mesh is weaved by plain weave.
