You can choose the appropriate specifications according to different needs and are suitable for various construction sites, such as bridges, houses, roads, etc.   Scaffold Plank Product Advantages: The unique drilling design of the construction steel springboard solves the problem of surface drainage and is suitable for construction under various weather conditions. When hot-dip galvanized steel springboards are used for construction, the number of steel pipes used to build the scaffolding can be appropriately reduced, which not only saves materials for the construction party but also improves construction efficiency. Scaffolding Steel Boards have great advantages not only in terms of materials but also in terms of economy. They reduce maintenance and are easy to use. They are popular in the construction industry and are indispensable equipment in the construction industry. Nowadays, the construction industry is in full swing, and there are many demands and requirements for these building materials, all of which promote each other. Scaffolding Steel Boards are fire-proof, sand-proof, light weight, corrosion- resistant, alkali-resistant and have high compressive strength. The concave and convex holes on the surface and the I-shaped design on both sides are particularly effective than similar products. The hole spacing is neat and standardized, and the appearance is beautiful and durable. Durable (can be used continuously for 6-8 years under normal construction). The unique sand leakage hole technology at the bottom prevents sand accumulation, and is especially suitable for use in the coating and sandblasting workshop of shipyards. When using scaffolding steel boards, the number of steel pipes used in scaffolding can be appropriately reduced and the construction efficiency can be improved. The price is lower than wooden boards, and 35%-40% of the investment can still be recovered after many years of scrapping. Features: 1. Galvanized steel scaffolding Planks have a high recycling rate, long service life, are easy to install and disassemble, and can still pay garbage disposal fees after being scrapped. 2. The unique convex hole design of the Scaffolding Steel Boards can not only reduce its own weight, but also prevent slipping and deformation. The I-shaped design on both sides increases the fastness and strength, prevents sand accumulation, and makes it beautiful, sturdy and durable. 3. The unique shape design of the Scaffolding Steel Board makes it easier to bundle, hoist and install, and it can be stacked neatly when not in use. 4. The scaffolding steel boards is made of cold-processed carbon steel. Through hot-dip galvanizing technology, the service life can reach about 5-8 years. 5. The use of scaffolding steel boards has become a trend at home and abroad, which has greatly improved the company's construction qualifications and brought about a big turnaround.
