joist steel corrugated guardrail, highway guardrail, waveform guardrail

The company's main sales products: corrugated guardrail, highway guardrail, joist steel corrugated guardrail, highway guardrail, waveform guardrail, wave beamGuardrail plate.waveform guardrail waveform column beam expansion is the main form of semi-rigid guardrail, it is a kind of corrugated steel guardrail plate joining together with each other and supported by the main column continuous structure. It used soil base, wire mesh fence, beam deformation to absorb impact energy, and force is out of control vehicle changing direction, back to normal driving direction, prevent the vehicle out, in order to protect the vehicles and passengers, reduce the loss caused by accidents. Waveform and beam guardrail steel is soft, strong ability to absorb collision energy, has a good line of sight induction function, can be coordinated with road alignment, beautiful appearance, can be used in the small radius curve in the road, the damage is easy to replace. Beam combination waveform guardrail can be used in the middle of the narrow space to bring. Vehicles for the outlet (bridge), may cause serious consequences extents, strengthen wave beam guardrail can choose. Waveform guardrail waveform guardrail utility model relates to a highway median openings with combination waveform steel guardrail plate activity type, the fence is made of corrugated steel fence panels and two slices of clamp put between two columns, two column clamp is installed between the two pieces of corrugated steel fence panels. During normal operation, the fence use plug pillar can be easily inserted into the opening set in advance of the plug hole, the role of isolation and protection, highway guardrail on the outside, at the same time take photograph echo, neat, beautiful. Vehicle collision to its, because of the corrugated steel guardrail plate collision resistant performance and energy absorption effect, is neither easy to crashed again at the same time for the vehicles and passengers staff have very good protection effect. When pavement maintenance or for other reasons need and tong, pull the opening of each barrier pillar can be easily removed and open up channels, facilitate the traffic. System principle: 1, the wave beam barrier is the main form of semi-rigid guardrail, it is a kind of corrugated steel guardrail plate joining together with each other and continuous structure supported by columns. 2, it used soil base, column, beam deformation to absorb impact energy, and force is out of control vehicle changing direction, back to normal driving direction, prevent the vehicle out, in order to protect the vehicles and passengers, reduce the loss caused by accidents. 3, waveform and beam guardrail steel is soft, strong ability to absorb collision energy, has a good line of sight induction function, can be coordinated with road alignment, beautiful shape, can be used in the small radius curve in the road, the damage is easy to replace. Double difform guardrail waveform guardrail common specification plate: 4320 * 310 * 85 * 3/4; Three difform guardrail board: 4320 * 506 * 85 * 3/4; Double wave column: 114 mm× 4.5 mm× Height; Three waves: the post 140 mm× 4.5 mm× Height; Waveform guardrail installation distance (column spacing is divided into 2 m spacing and 4 m spacing; Waveform guardrail column connected to the board edge way way has anti block type and tray type two kinds. Classification of waveform guardrail waveform beam guardrail generally according to the set location and anti-collision level for classification. According to the set location can be divided into roadside guardrail and median guardrail. According to the grades of collision avoidance can be divided into class A and class S. Belongs to enhanced s-class guardrail, applicable to roadside particularly dangerous road use, grade A for special roads. According to the grades of anti-collision in general can be divided into class A and class B. Grade A guardrail belongs to enhanced, suitable for roadside particularly dangerous sections, B is used for special roads. Wave beam guardrail products introduced: commonly used roadside wave beam guardrail according to the grades of collision avoidance can be divided into B, A, SB, SA, SS grade 5, highway crash barrier is A typical cold-formed steel products; Two guardrail plate commonly used specification is 4320 mm & times; 310 mm & times; 85 mm & times; Three-quarters of mm, for the post? 114/140 mm× 4.5 mm; Three waves guardrail board commonly used specification is 4320 mm & times; 506 mm & times; 85 mm & times; Three-quarters of mm, for the post? 130 mm & times; 130 mm & times; 6 mm. Waveform guardrail related parameters, column board width 310 mm, thickness: 3 mm, 4 mm. 1 t fence panels can be spread: 3 mm thickness of 80 m, 4 mm thick 61 meters. 3 mm thick heavy 12.3 tons per kilometer, 4 mm thick heavy 16.388 tons. Columns: roughness specifications Q114, Q140MM length according to requirement of 1.2 m, 1.4 m, 1.85 m, 2 m, 2.15 m, 2.27 m, the thickness is 4 MM / 4.5 MM. 3, with $250 per kilometer barrier plate. Column spacing of 4 meters, with 250 per kilometer, the columns, the end of 2, 250 cap, screw 250 sets, 250 bracket, control block 250.
