The High-mast Lamp is generally refers to the new lighting device which is composed of the steel taper light pole and the high power combination lamp frame of 15 meters or above.It consists of lamp holder, internal lamp, electric rod body and basic part.Lamp head modelling can according to user requirement, surroundings, lighting need specific and definite;The interior lamps are mainly composed of floodlights and projection lamps. The light source adopts NG400 high pressure sodium lamp, and the lighting radius is 60 meters.The bar body is usually a pyramid structure, which is made of steel plate, with a height of 15 to 40 meters, which consists of two to three sections.
Material characteristics
1. Beautiful appearance, large lighting area, good lighting effect, concentrated light, uniform illumination, small glare and easy to control and repair.
2. Applicable places: city square, station, wharf, highway, stadium, overpass, etc.
3. The lamp pole is a high quality steel plate by moulding into a multi - pyramid splicing steel rod, through hot galvanizing anti-corrosion treatment.
4. The lamp frame is made of high quality stainless steel.
5. Fasteners bolts and nuts are stainless steel.
6. Light source:400W-1000W sodium lamp.

Heat Treatment/Â Â Â Â Â Delivery Condition
Cold finished (hard)Â Â BK(+C)
Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation
Cold finished (soft)Â Â Â BKW(+LC)
The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding)
Cold finished and stress-relieved annealing BKS(+SR)
Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree.
Annealed   GBK(+A)
The last Cold forming process is followed by annealing in a controlled atmosphere.
Normalized  NBK(+N)
The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
