Nickel sintered mesh is a porous metal material made from multiple layers of high-purity nickel mesh through a high-temperature sintering process. The sintering process permanently bonds the metal mesh layers together, forming a solid and stable multilayer structure. Nickel sintered mesh combines the high electrical conductivity, excellent corrosion resistance, and superior mechanical properties of nickel, making it suitable for demanding industrial environments such as filtration, catalysis, battery applications, and high-temperature gas treatment.

Stainless Steel Sintered Wire Mesh is a composite mesh made from multiple layers of stainless steel wire mesh that are sintered together under high temperatures. This sintering process bonds the layers to form a unified material with high strength, stability, and uniform porosity. Due to its excellent filtration capabilities and mechanical strength, sintered metal mesh is widely used in petrochemical, pharmaceutical, food processing, and environmental applications that require precision filtration and long-term durability.

Pre-crimped wire mesh is a woven mesh product made from high-quality stainless steel wire that has been pre-crimped to form a wavy or patterned structure before weaving. This crimping process ensures that the pre-crimped wire mesh is more stable and tightly woven, providing excellent strength and durability. With outstanding corrosion resistance and structural stability, stainless steel crimped wire mesh is widely used for screening, filtration, partitioning, and architectural decoration.

Clog-resistant self-cleaning screen mesh provides effective solutions for sticky and moist materials. The unique crimped and bonded wire structure prevents material blockage, improves throughput, and guarantees consistent performance, especially in wet screening applications. Self-Cleaning Screens are advanced anti-blinding screening meshes engineered to reduce clogging, material buildup, and downtime in challenging screening conditions. Manufactured with specially crimped or independently vibrating wires, each wire moves freely during operation to prevent blinding, pegging, and blocking—particularly when handling damp, sticky, or fine materials.

Polyurethane elastic screens are high-performance industrial screening elements made from polyurethane (PU) with embedded steel cable or polyester mesh. They are primarily used for material grading, dehydration, and de-mediation processes in mining, metallurgy, coal, and building materials industries. Its core value lies in combining the excellent elasticity of polyurethane material with the tensile strength of steel wire. Key Features and Functions Polyurethane elastic screen is made of steel wire rope core covered with polyurethane layer as warp and weft wire, which is processed by heat fusion welding at a certain temperature.    

Piano wire screens—also known as high-tensile self-cleaning screens or harp wire screens —are engineered for applications where traditional woven wire mesh struggles with blinding, pegging, and clogging.  These screens use parallel high-tensile steel wires supported by polyurethane or steel cross members, allowing the wires to vibrate independently to release fines and prevent material from getting stuck. Compared with standard woven screens, piano wire screens deliver significantly higher open area, consistent stratification, and improved screening efficiency in wet, sticky, or fine materials. Applications of Piano Wire Screens Piano wire screens are widely used in the mining, aggregates, construction, recycling, and general industrial sectors, delivering excellent performance for screening wet, sticky, fine, or hard-to-process materials.

Fine PU Screens, also known as Polyurethane Fine Aperture Screen Panels, are high-precision screening media manufactured from high-performance polyurethane elastomer for critical fine material separation. Engineered for applications such as grading, dewatering, de-mediation, and desludging, they deliver precise screening of particles typically ranging from 0.1 mm to 3 mm. Widely used in mining, coal washing, and mineral processing, Fine PU Screens provide a durable, wear-resistant, and long-life alternative to traditional metal screen panels. Technical Specifications of Fine PU Screens Screen Slot Range: 0.045 mm – 3 mm Opening Rate: 15.25% – 46.51% Material: High-performance polyurethane elastomer Screen Type: Fine aperture / slot opening Panel Thickness: Customized according to screening capacity Installation System: Modular fastening, bolt-down, rail mounting

A Prestressed Anchorages consist of wedges, anchor head and bearing plate for transfer the post-tensioning force from the prestressing steel to the structure.  In addition, Its including all accessories for grouting. Furthermore, Stressing anchorage is the most common form of post-tensioning system. It is widely used in concrete structure and soil / rock retaining walls. post tensioning anchorages consist of wedge, anchor head, bearing plate and spiral reinforcement. Flat Anchor: The Flat Anchor accommodates a maximum of five strands in a single plane, allowing them to deviate into one oval duct. This design is primarily intended for use in thin structural members. It is commonly employed in the transverse post-tensioning of the top slab in box-girder bridges and prestressed flat slabs. The system connects strands that run through steel or flat corrugated galvanized steel ducts, which are manufactured in our facility. Each strand is individually stressed using a mono-strand jack.

In the application of pre-tensioned concrete, the pre-stressed steel wire is initially tensioned to approximately 70 to 80% of the minimum specified breaking load of the steel wire before the concrete is cast. Once the concrete sets to a certain degree, the pre-tensioned steel wire is released, and this induces compressive stress in the concrete. This compressive stress helps offset the tensile stress caused by the loads acting on the concrete member. For effective pre-tensioning, it is crucial to establish a strong bond between the steel wire/bar and the concrete. This bond allows the desired compressive force to be efficiently transferred from the steel wire to the concrete. One method to improve the bond strength and achieve a consistently low transmission length is by introducing regular indentations of a specified shape on the surface of the steel wire/bar. These indentations can be slotted in opposite or 120-degree or 90-degree planes. To create indented steel wire or rod, a process known in the industry is to perform intermittent indentation on the wire's surface using appropriate indenting rolls. Typically, this indentation process takes place on a wire- drawing machine, where the wire is pulled through the indenting rolls to achieve the desired pattern.
