Production is the basis of high quality high lamp technology

Our company to every customers purchase products confidence believe you choose our company is the recognition of our company and our company's support and attention, you can have is the biggest support to us. High lamp manufacturers of small make up to introduce today is about light, technical requirements:

( 1) Material: light pole steel material for baosteel, wisco, three steel, anshan iron and steel and other metal special SS400 low silicon low carbon high strength steel ( 如果≤ 0. 04%) , the thickness is not less than 6 mm, the bottom flange thickness & ge; 20mm。 Requirements to ensure that the end of hot dip galvanized hardness and adhesion, the surface is not black. Accord with a country or enterprise standards, and provide the steel supply contract and certificate of quality of steel. Project-light lamp mounting bracket for the side channel steel, lamp plate edge groove down the specification for 40 mm * 80 mm, lamp plate middle bracket for 40 mm * 60 mm, the thickness of 3. 5 mm, lamp plate diameter is 1800 mm.

　　( 2) Design: light pole structure and basic structure size calculation, in accordance with the tenderer for the appearance of the shape and structure parameters according to the seismic magnitude 7, fortification was 12th level; Main rod is twelve sprayed, light pole as the transportation is convenient, high light pole adopts the plug type, every day, splice length shall not be less than 500 mm, light pole plug after good fit clearance shall not be greater than 3 mm, and is equipped with the spacing device of reliable and strong device. Light pole design should match light pole, the basis of the foundation with concrete structure, based on the left a fixed light pole anchor bolt and the flange plate fixed anchor bolts in the flange; Based embedded within the in and out of the cable threading pipe, threading pipe using hot dip galvanized steel pipe, and mark the foundation reinforcement, concrete strength grade, such as construction drawing, basic meet GBJ11 - 89 building seismic design code; In addition to the foundation bolt of the rest all fasteners are made of stainless steel and reliable durable easy to operate. All kinds of nut fastening, should add washer and spring washer, tighten the screw with nut should not be less than two pitch. Set the lightning rod at the top, long needle 0. 5 meters, lamps and lanterns is based around a grounding system, grounding resistance is not greater than 30 European, grounding electrodes by 2. 5 m long, 50 * 5 galvanized Angle steel, galvanized flat steel the ends of the earth line is 25 * 4. Grounding body with light pole, lamp plate, reliable connection, such as distribution box forming solid conductive path. Manufacturer to provide according to the light pole figure of the rod body figure modelling and stress calculation, including embedded screw, flange, such as calculation, provide the technical drawings and foundation of light pole details ( Based embedded within the basic profile, cable pipe drawing, bolts and high lamp based embedded parts connection diagram, drawing, etc. ) 。

　　( 3) Welding process: should use argon gas protection welding, the rod body should be without any welding, weld formation, without any weld defects. In line with the GB/T3323 - welding seam More than 1987 level iii standard, as deep as 805, required to provide the weld inspection reports.

　　( 4) Hot galvanizing technology: lighting inside and outside surface, lamp plate and the surface of all metal parts shall be hot-dip zinc treatment. Requirement of galvanized layer, thickness not less than 65 & mu; m; Galvanized surface should be smooth and beautiful. In accordance with GB/T13912 - Galvanized 92 standard, and provide test report.

　　( 5) Should be passivation after coating process: galvanized, plastic spraying, good adhesion, thickness & ge; 80μ m( Color is white) 。 Import high quality plastic powder coating should be adopted. Accord with ASTMD3359 - 83 standard, and provide the coating test report.
