Steel Raised Expanded Metal

Steel Raised Expanded Metal

Steel Raised Expanded Metal is a versatile and durable material made by slitting and stretching steel sheets to create a mesh-like pattern with raised openings. It offers excellent strength, rigidity, and skid resistance, making it ideal for applications such as industrial walkways, platforms, and security fencing. The raised design enhances traction and provides an aesthetically pleasing appearance while allowing for the passage of light, air, and sound. Suitable for both interior and exterior use, it is corrosion-resistant and can be coated or painted to fit specific design requirements.

CHEMICAL COMPOSITION

  • The chemical composition of this category predominantly consists of high-strength steel with carbon content tailored for enhanced durability and performance. Additional elements such as manganese and silicon are included to improve tensile strength and hardness, while trace amounts of phosphorus and sulfur are controlled to minimize brittleness. The presence of nickel and chromium contributes to corrosion resistance and overall metallurgical stability, ensuring suitability for various industrial applications.

MECHANICAL INFORMATION

  • This product category consists of expanded metal sheets available in various sizes, which are primarily defined by parameters such as design size, opening size, strand size, and overall material thickness. Each variant is characterized by specific measurements of Short Way of Design (SWD) and Long Way of Design (LWD), determining the sheet's pattern and structural integrity. Available sizes include openings ranging from 1/4 inch to 1-1/2 inches, with strand thicknesses varying from 0.042 inches to 0.127 inches, impacting both weight and strength. The number of diamonds per linear foot, an indicator of mesh density, varies across configurations, affecting the sheet's open area percentage, which ranges from 43% to 85%. Nominal weight also varies, from 54 lbs to 180 lbs per 100 square feet, influenced by the combination of design, thickness, and material strand specifications. The overall thickness extends slightly beyond the strand thickness, accommodating the expanded configuration. These expanded metal sheets are versatile, suitable for applications requiring diverse combinations of open area and strength.

AVAILABLE SIZES

  • The available sizes for this category include various combinations characterized by different design sizes and details. These sizes feature distinct opening and strand dimensions, with styles measured in inches such as 1/4" x #18, 1/2" x #18, 1/2" x #16, 1/2" x #13, 3/4" x #16, 3/4" x #13, 3/4" x #9, 1-1/2" x #13, and 1-1/2" x #9. The specifications cover measurements such as SWD (Short Way of Design) ranging from 0.250 to 1.330 inches, LWD (Long Way of Design) from 1.000 to 3.000 inches, and corresponding strand widths and thicknesses defining the structural integrity of each style. With diamonds per foot varying from 9 to 48 and open areas spanning 43% to 85%, each design delivers unique properties suited for specific applications. Nominal weight per hundred square feet is detailed, ensuring accurate assessment of material requirements, while minimum thickness and overall thickness parameters ensure each product serves its intended use effectively, highlighting the versatility of available sizes.
