At MULTI, we understand that structural steel tubing is an essential element for constructions requiring maximum strength and durability, both in industrial and residential projects. To that end, we offer two main types through our Tuboacero line: black structural tubing and galvanized structural tubing, each designed to perform specific functions in diverse environments.
With decades of experience, we are proud to be the trusted choice for architects, engineers, and builders throughout Central America.
Black structural tubing: strength and aesthetic adaptability

Our black structural tubing stands out for its robustness and adaptability to different aesthetic finishes. Manufactured in hot-rolled or black form, this tubing allows for additional varnishing, painting, cutting, or welding processes to improve its strength and appearance. This tubing comes in square and rectangular shapes.
By complying with the ASTM A500 standard for structural tubing, we guarantee a high-quality product, ideal for gate and fence applications. Thanks to its ability to absorb paint well, it allows for customizable finishes and adapts to any architectural design.
Galvanized structural piping: corrosion protection

On the other hand, our galvanized structural tubing offers a unique advantage in terms of rust resistance. Thanks to its coating, this tubing withstands extreme weather conditions, making it the preferred choice for outdoor projects such as pergolas, wine cellars, and industrial warehouses. With a rust-resistant lifespan of up to 20 years, our galvanized tubing ensures that structures maintain their structural and visual integrity over time, even in environments with high humidity and exposure to the elements.
Both types of structural piping, both black and galvanized, are manufactured in various shapes, such as square and rectangular. The choice between these shapes depends on the aesthetic and functional focus of the project, offering a choice between the elegance of galvanized piping and the decorative flexibility of black piping.
Uses and advantages in architectural and industrial projects
Our structural steel pipes are suitable for a variety of applications due to their strength, durability, and design flexibility. Galvanized pipe is widely used in various applications and industries due to its weather resistance, and is also used in support structures such as beams and frames of industrial buildings. Black pipe, meanwhile, is highly customizable and ideal for projects where aesthetics are a priority, such as decorative facades and doors.
Our offer stands out in the market for meeting the estándares internacionales ASTM, which ensures that our products are designed to withstand loads and environmental wear and tear. With a production line that covers all formats and dimensions, at MULTI we have established ourselves as a trusted supplier for professionals seeking quality and customization in their construction projects.
At MULTI, we guarantee that structural steel tubing, in both black and galvanized versions, represents a highly reliable and versatile solution for architectural and industrial projects. Our focus on innovation and compliance with international standards positions us as the steel leader that understands the needs of today's market, providing adaptable, high-performance solutions for the success of each project.
