Tensile strength generally refers to steel or welded steel mesh, and the compressive strength of concrete structures is talking or rocks. After the tensile strength during stretching, the material after yielding the stage to strengthen the stage with significantly reduced transverse cross-sectional dimension in the pull-off exposure to the most vigorous (P), divided by the original specimen cross-sectional area (b * stress (σ) h) the resulting black interior wire mesh piece, known as the tensile strength or ultimate strength (σb), in units of N / mm2 (MPa). It indicates that the material to resist damage maximum capacity under tension. The formula is: σ = P / b * h (. Where P is the maximum failure load; unit N; b is the sample width in mm; h is the sample thickness, unit cm) refers to a material tensile strength to pull off the front subject to the greatest stress. When the steel yield to a certain extent, due to the internal grain rearrange its ability to resist deformation increase again, this time distortion has developed rapidly, but it can only be improved with the increase of stress until the stress reaches the maximum value. Since then, the ability of steel to resist deformation significantly reduced, and large plastic deformation occurs at the weakest point, where the specimen cross section of rapidly shrinking, there necking facades black wire mesh piece, until fracture failure. Steel pulled by the maximum stress value is called before breaking strength or ultimate tensile strength. Greenhouse nursery bed main structure hot-dip galvanized steel mesh; galvanized steel; hot galvanized pipe scaffold; frame made of aluminum alloy profiles; height direction can be fine-tuned; with anti-turn limit device, all unilateral translation up to 300MM, can produce about 0.6 meters of operating channel between any two seedbed, nursery seedbed network products are all high quality low carbon steel wire, the latest large-scale machine assembly line, mesh joint, welding head by the line-by single spot welding, although many houses black wire mesh piece, but the quality is better when employment. Mobile seedbed specifications according greenhouse width length, length can be set as according to user requirements. General recommendations about 1.7 m width, length not exceeding 25 m.
