Pre-galvanized Steel Pipe

TYTSTEEL: your professional Pre-galvanized Steel Pipe manufacturer & supplier

TYTSTEEL is a professional manufacturer of galvanized steel pipes in China. All the pipes are high-frequency welded. You can find galvanized steel pipes in all sizes (custom diameters, thicknesses, lengths) and materials.

There are hot-dip galvanized steel pipes and pre-galvanized steel pipes. We produce both types of galvanized steel pipes according to BS 1387, EN 39, JIS 3444, and ASTM A53/A53M standards. BV or SGS inspection is available if you require.

All of our galvanized steel pipes are tested for mechanical properties after production is completed. The test includes testing the tensile strength, yield strength, elongation, and chemical elements of the galvanized steel pipe to ensure that its mechanical properties meet the standard requirements. It can meet at least 8 hours corrosion free in salt spray test.

pre-galvanized pipe Ultimate Guide

pre-galvanized pipe specification&size

What is pre-galvanized steel pipe?

Pre-galvanized steel pipe is a welded steel pipe with a zinc coating of 10-50 g/m2. Pre-galvanizing is accomplished by passing the steel through a molten zinc bath and then removing any excess zinc with a stream of air.

What is the difference between pre-galvanized and galvanized?

The main difference between pre-galvanized and galvanized steel is the timing of the galvanizing process.

Pre-galvanized steel is galvanized before the steel is formed into its final shape. The steel is coated with a thin layer of zinc that provides some protection against rust and corrosion, but the coating is not as thick or durable as galvanized steel.

Galvanized steel, on the other hand, is steel that has been formed into its final shape and then coated with a thicker layer of zinc. The galvanizing process involves immersing the steel in a molten zinc solution, which creates a thick, durable layer of zinc on the surface of the steel. This layer of zinc provides superior protection against rust and corrosion, making galvanized steel a popular choice for outdoor applications such as fencing, roofing and structural support.

What does pre-galvanized mean?

Pre-galvanized steel is steel that has been coated with a layer of zinc prior to forming its final shape. Quite simply, the metal is galvanized to give it its corrosion protection properties. Without a protective zinc coating, the metal will continue to be exposed to the elements and may oxidize and corrode more quickly.

The pre-galvanizing process involves passing the steel through a molten zinc bath that coats the steel surface with a thin layer of zinc. This layer of zinc provides some protection against rust and corrosion, but it is not as thick or durable as the layer of zinc that is applied to the steel in the post-galvanizing process.

This method is very similar to hot-dip galvanizing, but is performed in a steel mill and is typically used on materials that already have a specific shape. Pre-galvanizing involves rolling the sheet metal through a clean process similar to the hot-dip galvanizing process. The metal is then passed through a pool of hot, liquid zinc and then backflushed.

An advantage of this method is that large rolls of sheet metal can be galvanized quickly and with a more uniform coating than hot dip galvanizing.
