Matkel typically offers steel tube diameters from 22 mm to 219 mm, with wall thicknesses from 1.5 mm to 6 mm depending on the order. Custom sizes may be available for structural frames, gates, or doors. Specify the required size for Saudi project specifications to ensure the right strength and fit.
Black steel tubes can rust when exposed to moisture, so they usually need paint, primer, or a protective coating. For coastal areas such as Jeddah or Dammam, pre-treatment or a corrosion-resistant finish is recommended before installation to reduce salt air damage.
Black steel tubes have a dark surface and are usually used for structural frames or doors after painting. Coated tubes have a smoother, cleaner finish and are better for visible works. Choose based on the project use, required strength, and how easy the final finish should be.
Steel tube weight depends on diameter, wall thickness, and length. A thicker tube weighs more than a thinner one even with the same diameter. For large orders, use the actual weight shown on the delivery invoice, especially when pricing is based on the total tonnage.
Steel tube pricing depends on size, wall thickness, and quantity. Matkel may offer contractor-friendly rates for projects in Riyadh, Jeddah, or Dammam. The final price also depends on loading and transport, so request a full quote that includes delivery to your project site.
