How is the theoretical weight of  galvanized steel calculated?

To know how the weight of the zinc steel guardrail comes from, you must first know what kind of pipe is used for your zinc steel guardrail. What is the thickness? You can know how much the weight of the zinc steel guardrail is used. Take our factory. The production of zinc steel guardrails is an example. I will introduce you how to get the weight of it.

Square tube (side length - thickness) * 4 * thickness * 0.00785 = weight of one meter, so that the profile is generally 6 meters long, so the weight of one meter * 6 is the weight of a 6 meter profile.

We use the zinc steel guardrail spot produced by our factory as an example to apply the formula. The height is 1.5 meters and the length is 3 meters of zinc steel guardrail. The column is 50*0.9, the crossbar is 40*0.7, and the vertical rod is 19*19. *0.6. The above thickness is pre-plastic.

The weight of the column: (50-0.9)*4*0.9*0.00785*6=8.33 kg, the 6-meter profile is 1.5 meters higher than the 4, so the weight of the 1.5-meter-high column is: 2.08 kg.

The weight of the horizontal pipe: (40-0.7)*4*0.7*0.00785*6=5.2 kg, the 6-meter profile is 2 meters long and the weight of the three beams is 5.2*1.5=7.8 kg.

The weight of the vertical rod: (19-0.6)*4*0.6*0.00785*6=2.1 kg, the 6-meter profile has four vertical bars with a height of 1.5 meters, and the zinc steel guardrail requires 20 vertical bars. The weight is: 10.5 kg.

The weight of the set of zinc steel guardrails is the weight of a column + the weight of 3 weights + the weight of 20 vertical bars is the weight of a set: 20.1 kg, plus the weight of one piece of all accessories is about 7 kg. .
