Avoid Leita detailed price list

Lightning rod production and installation of all metal parts shall be galvanized zinc coating to protect the operation. Galvanized steel tube production tip, the wall thickness of not less than 3mm, needle length must not be less than 70mm brush tin lightning rod should be mounted vertically firmly. Verticality tolerance of 3/1000. Welding requires welding lap welding should be used, its lap length must meet the following requirements: Flat for 2 times the width (and at least three edge welding). Round 6 times its diameter. When connecting round and flat, having a length of 6 times the diameter of round steel. Lightning rod generally use round or made pipe, with a diameter not less than the following values: a lightning rod is generally independent galvanized steel bar with a diameter of 19mm. b lightning rod on the roof using 25mm diameter galvanized steel. c tower top lightning rod made of galvanized steel d 25mm or 40mm diameter chimney lightning rod on top of galvanized steel bar with a diameter of 25mm or 40mm diameter galvanized steel ring with a diameter of 12mm e lightning galvanized steel bar or a cross-section of 100mm2 galvanized flat steel its thickness should be 4mm 1, to avoid Leita lightning rod production 1) According to the drawings in the basis for the civil construction lightning rod, good anchor bolts embedded like. 2) Press material design requirements of the desired length, middle and lower three sections cutting. Weld seam sharpened, rinse tin if the needle used in the steel production, the first section of pipe on the end of sawn serrated tip income after hand hammer, and the other end in the next two sections to find a straight weld. 2, to avoid Leita lightning rod installed on the bearing plate fixed on the embedded anchor bolts, welded on a rib, then the lightning rod standing, looking straight alignment after spot welding, and then corrected, the welding the other three threats board. Finally, the deflectors welded to the floor, clearing brush rust coating. 3, to avoid Leita bracket angle bracket should dovetail its underground injection depth of not less than 100mm, flat and round bracket depth of not less than 80mm. All brackets must be strong, mortar full, smooth vertical and horizontal. Various top bracket of lightning protection devices should generally be from the surface of the building 100mm; grounding line stand at the top level should be away from the wall bracket 20mm spaced not more than 1m (concrete seat no more than 2m);. Vertical spacing of not more than 1.5m. Each pitch should be uniform, tolerance 30mm. The corner on both sides of the bracket from the corner of the center is not more than 250mm. Should stand straight. Check the level of each segment tolerance 3/1000 2m, 3m check verticality every segment tolerance 2/1000; but the full-length deviation of not more than 10mm. Stents and other iron items should be treated with preservatives. NOTE stent buried all cement mortar, the mixing ratio of not less than 1: 2. Bracket as far as possible with the structure embedded bracket or iron construction. Elastic line and sub-file be positioned according to the design requirements. A hand hammer. Tick ??chisel were holes, the size should be consistent inside and outside. Note first buried on a straight line at both ends of the stent, and then buried in a straight line with a lead strands note other bracket. NOTE buried preceded the wet cave with irrigated. As with concrete supports, concrete bearing sub-file gracefully. First pull both ends of a straight line between the bracket and the other with mortar seat looking straight. If you have embedded iron parapet reservation, you can find direct method bracket welded directly to iron, stand with the former. Lightning rod production and pay attention to the quality of the installation: a no full welding, flux process is not clean, drain brush rust. Should promptly be welding, coating will knock down, brush the rust. Curved needle, verticality installation beyond tolerance. Weight new needle should be straight, in line with the requirements before installation entrances and separate lightning rod grounding devices and protection from the road or building does not comply. Its distance should be greater than 3m, when less than 3m, equalizing measures should be taken or to lay gravel or asphalt. Mr. Liu Juntao (manager) Mobile: 18601999201 Tel: 86-0318-4433329
