Steel gangboards for construction ships have fireproof, sandproof, lightweight, alkali-resistant, high compressive strength, surface concave convex holes, and double-sided I-shaped design effects that are more significant than similar products. The hole spacing is neat, the shape is standardized, it is beautiful, and it is durable (it can be used continuously for 6–8 years under normal construction). The special sand leakage process on the bottom surface plays a role in preventing sand accumulation and is particularly suitable for use in sandblasting workshops in shipyards. By using steel springboards, the number of steel pipes used for scaffolding can be appropriately reduced, thereby improving the efficiency of the installation. Compared to woodblocks, it has a lower price and can still recoup 35%–40% of the investment after many years.
