What about the materials for the public seat?

Answer:

Plastic。 Because the plastic material is easy to process and rich in color, it is generally suitable for making the seat surface and making foot with other materials. But the plastic corrosion changes, poor strength and durability. In order to change the characteristics of the material, plastic and concrete composite materials can be used to strengthen the strength of the material.
Metallic materials。 Mainly cast iron, cast iron has a heavy sense and durability, can be free to shape. There are also stainless steel and aluminum alloy materials, because of its high heat and cold conductivity, it is difficult to adapt to seating requirements. Now, because of the development of punching technology, the sheet metal can be made into reticular structure, which has better heat dissipation and can be used on the seat surface. Aluminum alloy, small caliber steel tube can be processed into light and zigzag shapes.
Coagulation. Strong water absorption, easy weathering, poor sense of touch, can be used in conjunction with other materials.(4) pottery. The ceramic material by firing into the kiln process due to limited, its size is not too large, easy to deformation, it is difficult to make complex shapes.
) stone. It is advisable to use granite and other stone materials with turns. The stone has the rigidity, the resistance to government, the impact resistance, the decoration effect is better, European use is more common. Because the stone processing technology is limited, its shape change is few.
) wood. Good sense of touch, material processing, but its poor durability (after heating, preservative treatment of wood, also has a strong durability). With the improvement of wood bonding technology and bending technology, the shape of chair has been diversified.
