Works such as cutting reinforcement for stairs, super -strength and hardened, as well as its knitting or welding, must be performed by professionals. Cutting is most often carried out by a gas cutter, or with the help of a special effective and universal air-plasma equipment. Reinforced concrete stairs are suitable for almost every structure. They are not subject to corrosion, like metal ones, do not rot and do not burn, like a tree, while the concrete stairs are silent, and their strength only increases over time. All kinds of structures can be built from reinforced concrete, and made by the skillful hands of real masters, they will not only be convenient and ergonomic, but also quite attractive.
