Field tests show an indoor temperature drop of 4–6 °C and an energy-use reduction of 24 %–36 %.Structural Safety & StabilityPremium raw materials and a precise process give expanded metal uniform openings, a flat surface and non-deformed edges. Installed as expanded metal on an architectural facade, the system is solid, durable and safe.Apply For Green Building LabelThe expanded metal has earned two green-building materials certificates (Green Building Innovative Technology and Low-Carbon Construction Method) and a full life-cycle carbon audit. Used as an architectural facade or green wall, it helps projects secure green-building labels, win ESG tenders and obtain government subsidies.Daylighting & VentilationThe continuous diamond pattern of expanded metal maintains natural light and airflow while still improving thermal insulation and energy efficiency. such as hot-dip galvanizing, metal electroplating, powder coating, and fluorocarbon painting.Versatile FabricationAn expanded metal sheet can be hot-dip galvanized, metal-plated, powder-coated or plastic-over-molded. It can also be cut, spliced or framed to create layered, expressive facades.

Perforated Metal Mesh, Diamond Mesh, Welded Wire Mesh, Corrugated MeshShang Kai Steel also provides four types of metal mesh building materials: perforated metal mesh, diamond mesh, welded wire mesh, and corrugated mesh. In pursuit of high quality, Shang Kai Steel adheres to the following four core principles for all metal mesh products:1. High-quality raw materials:All metal mesh is made exclusively from premium-grade steel supplied by China Steel Corporation (CSC). Material batch certificates and source documentation can be provided upon request.2. High-precision manufacturing:Each metal mesh product is produced through a highly standardized manufacturing process. Dimensional tolerances are strictly controlled within ±3 mm, which reduces time and labor costs during construction and installation.3. Strict quality inspection:Before shipping, every metal mesh product undergoes a three-step inspection process. First, a visual check is conducted to ensure the mesh surface is flat, apertures are uniform, and edges are free from cracks or burrs. This is followed by dimensional testing to confirm that length, width, thickness, and opening sizes fall within specification. Finally, a random sampling inspection is carried out in the warehouse before packaging begins.4. Protective packaging and logistics:To prevent deformation or scratching during transport, the metal mesh is layered with protective materials, stacked on pallets, and wrapped with waterproof film. A trusted logistics network handles delivery, optimizing routes based on customer requirements to ensure timely and secure arrival.

Metal Stay-In-Place Formwork, Metal High-Rib Formwork, Steel Lintels, Steel Edge Stop Strips, Plaster Corner Beads, Structural Construction, Base Layer Reinforcement And Adhesion, Corner Edge Protection.Shang Kai Steel provides five types of high-quality auxiliary building materials for construction engineering, designed for three major applications: formwork installation, plastering base preparation, and detailed protective finishing. The product lineup includes metal stay-in-place formwork, reinforced metal mesh, steel edge stop strips, steel lintels, and plaster corner beads.1. Shang Kai Steel’s auxiliary construction materials offer the following three key features:2. Selection of metal materials: All auxiliary materials are made strictly from primary-grade metal supplied by China Steel Corporation (CSC). To ensure traceability of source and quality, Shang Kai Steel can provide material batch certificates for clients, construction supervisors, and engineering teams to verify.3. High-precision manufacturing: All production equipment at Shangkai Steel is custom-built. Standardized processes are applied in the manufacturing of auxiliary construction materials: the mesh surfaces remain flat and intact, plaster corner beads have clean and accurate bends, and all product dimensions are controlled within a ±3 mm tolerance. This greatly facilitates construction and installation, especially in alignment processes, reducing both time and labor costs.4. Compliance with international standards: Shangkai Steel manufactures auxiliary construction materials that comply with regional and international standards, including CNS (Taiwan National Standards), JIS (Japanese Industrial Standards), BS (British Standards), ASTM (American Society for Testing and Materials), and AS/NZS (Australian/New Zealand Standards).Shang Kai Steel categorizes its five types of auxiliary building materials into three main application areas: structural construction, base layer reinforcement and adhesion, and corner edge protection. Please refer to the following based on your needs:1. Structural ConstructionMetal Stay-in-Place Formwork:Also known as metal high-rib formwork, Shangkai Steel’s stay-in-place formwork is primarily used to support and define the shape and size of cast-in-place concrete areas. Its key feature is that, once the concrete is poured and cured, the formwork remains permanently embedded in the structure. This reduces the cost of formwork removal and is commonly used in structural elements requiring long-term stability.Steel Lintels:Shangkai Steel’s steel lintels are mainly used above openings such as doors and windows. They are designed to bear the load of the materials above and provide strength and stability, preventing sagging, cracking, or deformation at structural openings.2. Base Layer Reinforcement and AdhesionReinforced Metal Mesh:Shangkai Steel’s reinforced metal mesh combines expanded metal mesh with transverse rib structures. It is primarily laid over the substrate before plastering to enhance mortar adhesion and prevent cracking caused by structural movement or temperature variation. It is especially effective for walls, ceilings, and curved surfaces where surface stability and smoothness are critical.3. Corner Edge ProtectionSteel Edge Stop Strips:Lightweight and easy to install, Shangkai Steel’s steel edge stop strips are used during plastering to define clean, sharp boundaries—especially at edges and joints—to prevent overflow and ensure a neat finish. They are essential for both interior and exterior wall projects.Plaster Corner Beads:Designed for protecting and shaping wall corners, columns, and window edges, these corner beads are installed prior to plastering. They help define clean angles and offer strong impact resistance, preventing cracks or chipping at corners and maintaining a sharp, aesthetically pleasing edge.
