There are mainly stone columns, cast iron columns, steel columns, wooden columns and stainless steel columns, among which stone columns are the most commonly used. Stone pillars are natural and beautiful, hard and durable, and will not be affected by weathering and corrosion. Steel columns and stainless steel columns have better durability and wind pressure resistance, but the cost is higher. The material selection of doorposts should be comprehensively considered according to the actual needs and budget.
The maintenance of doorposts can not be ignored. First of all, clean the dust and stains on the surface of the doorpost regularly, and do not use corrosive and abrasive cleaners. If the doorpost is found to be deformed or cracked, it needs to be repaired or replaced in time to avoid affecting the safety of the whole building. In addition, it is necessary to strengthen the inspection and maintenance of the gate post to ensure the overall stability and safety of the gate when there is strong wind or heavy rain.
