Providing and fixing spring post made of special PU (Poly Urethane) material should having the following features for durability and performance: - 1. The body of spring post should be made of virgin special flexible material PU (Polyurethane). 2. It can be quickly retsored to its original state without doing any damage to spring post as well as vehicles in case of high - speed collision by vehicles. 3. Two bands of special heat transfer tape/high quality tape adhesive of minimum 70 mm must be pasted on the spring post for better and clear visiblity in the night. 4. It should keep excellent, mechanical and chemical propertoes such as impact resisitance and tensile strength to withstand in very hot or very cold temperatures. 5. It should have ultra violet stablizer so that it is not discoloured. 6. It should be in three different parts: upper tubuler part should be made out of PU & two bottom parts should be made out of ABS (Astronitrilite Butadine Styrene). 7. All three parts should be assembled together with the help of three nuts and bolts. 8. Specialy epoxy bond is used to fix the spring post with road surface. The bond should be so strong that post will not be deviated by strong impact after installation. 9. Dimensions : Length 710 mm, upper dia 80 mm & bottom dia is 210 mm. Weight of the upper body is 1100 gms, outer/inner part (lower part) 500 gms and weight of nuts/bolts 180 gms approx. Total weight of the spring post should not be less than 1800 gms approx.
