How to choose the proper structural steel pipe for your project

As a rule, each project is judged on its use of structural steel pipes from both an architectural and structural engineering perspective. It is believed that each project should be budgeted before your project starts. Steel pipe remains much cost effective compared with many other construction materials for over more than 30 years. Besides, structural steel pipe is considered an environment friendly building material in construction industry. Although the steel pipe price is not so stable in the market, this is still comparatively lower than the ready-mix concrete prices in the same period. Plus the fact that you don’t need highly skilled professionals to install your metal building at the site, the cost for the actual installation is definitely much lower.

Galvanized steel pipe generally has the rational cost effective in the market. Unlike other structural steel materials, galvanized steel is immediately ready for use when it is delivered. No additional preparation of the surface is required, no time-consuming inspections, additional painting or coatings are needed. Once the structure is assembled, contractors can immediately begin the next stage of construction without having to worry about the galvanized steel materials. Testing and studies have revealed that the average life expectancy for galvanized steel used as a typical structure material is well beyond 50 years in a rural environment and 20-25 years or more in an extreme urban or coastal setting. In that regard, contractors can confidently use this product in project.

Rectangular steel pipe is one member of the hollow structural sections which are metal profiles with square or rectangular tube section. Rectangular hollow sections are cold formed and welded from either hot rolled, cold rolled, pre-galvanized or stainless steel. ASTM A500 is the most common steel specification for hollow structural section in the current steel pipe market around the world. This specification is for cold formed welded and seamless carbon steel tubing in round, square and rectangular shapes. ASTM A501 is another standard for hot formed steel tubing. Rectangular steel pipe has many uses such as structural applications in residential, commercial and industrial construction. Besides, as the flat square surfaces of rectangular steel pipe has the ability to ease construction, they are sometimes preferred for architectural aesthetics in exposed structures. Today, rectangular steel pipes have also become very popular in many forms of construction and other structural & mechanical applications.
