What material is the lamppost made of?

In lamp posts, steel plates are generally coiled rods, which are galvanized and sprayed with plastic after welding. Skeleton sculptures are generally iron skeletons, galvanized and sprayed with plastic, and some are stainless steel.

1, stainless steel lamp pole, by hot dip galvanizing surface treatment, the service life of hot dip galvanized products meeting international standards can reach 15 years. Mostly used in courtyards, communities, parks and other places.

2. The surface of the iron lamp pole is sprayed, painted or dusted, and its service life is 3-5 years. Generally, there are many iron poles for road lighting.

3. The aluminum alloy lamp pole is made of high-strength aluminum alloy, which not only protects the safety of personnel, but also has high strength, corrosion resistance for more than 50 years, and does not need any surface treatment, which is very beautiful. Looks more upscale.

Technical requirements:

1, the surface of the lamp post is smooth, and there can be no cracks, missing welding, continuous blowholes, undercut and inequality. The linear error of the center line of the lamp post shall not exceed 0.02% of the length of the post, and the appearance of the post shall be free from unevenness and traces, and the appearance of the post shall be free from obvious defects.

2. The welding mode of the lamp pole is automatic sub-arc welding and ultrasonic flaw detection, which meets the requirements of welding standard GBL1345 Ⅱ II. The connection mode of lamp post socket is fixed by nail piercing and top wire.

3. The lamp pole is treated with hot dip galvanizing, and the zinc layer is not less than 75 microns. The surface is practical and smooth, with basically the same color. After hammering test, it will not peel off or fall off, and the galvanized life will not be less than 20 years.
