RTU Support Welding Specialists in Colorado Springs and Denver
When it comes to the installation of Roof Top Units (RTUs) on large buildings such as schools, commercial establishments, or churches in Colorado Springs, Denver, or Pueblo, proper support is essential. At Top Peak Welding, we understand the critical role that RTU supports play in maintaining the safety and functionality of these HVAC systems. Our expertise in RTU support welding ensures that your metal roof curbs are up to the task, providing a sturdy and reliable foundation for your rooftop units, even in Colorado's challenging climate. Hotels, industrial buildings, and offices all require some kind of support for roof equipment and we're ready for those projects.

Understanding RTU Reinforcement
RTU support systems, also known as RTU curbs or metal roof curbs, are designed to reinforce and stabilize roof top units. These supports are crucial because RTUs are often large, heavy, and require a robust base to ensure they do not compromise the integrity of the building’s metal roof deck. In Colorado's climate, which includes heavy snowfall and high winds, proper RTU reinforcement is vital to prevent potential hazards and maintain the efficiency of your roof top HVAC units.
We handle small- and large-scale structural work but often roof curb work is considered secondary structural. It doesn't necessarily have a load bearing feature for the building but it serves as a vital support to transfer the weight of the unit to the roof joists so nothing comes crashing down through the building. We can do retrofit work for existing structures, build and install new supports, plus replace braces at the same time equipment is getting replaced on a building. Just let us know your needs and we'll determine the specs required so we can offer a competitive price on welding in Colorado.
The Importance of RTU Support Welding
RTU support welding is a specialized process that involves fabricating and installing steel support frames for rooftop units. Whether using angle irons, steel beams, or other support braces, properly supporting any heavy equipment is essential for several reasons:
Safety and Stability: A well-welded RTU frame provides the necessary support to prevent the unit from shifting, falling, or lifting during heavy winds. In Colorado’s varying weather conditions, this stability is crucial for preventing damage to the building and ensuring the safety of personnel and visitors, even during harsh weather conditions.
Durability: Steel support frames are designed to withstand Colorado’s extreme weather conditions. Whether it’s heavy snowfall or strong winds, our frames are built to endure and keep your mechanical equipment securely in place over time.
Accessibility: Proper RTU structural support systems also facilitate easier access for maintenance and repairs. A stable base allows technicians to perform necessary servicing without compromising safety or risking damage to the RTU or the building.

RTU Support Frames for Small and Large Commercial Units
Top Peak Welding fabricates RTU reinforcements for a wide range of commercial rooftop units, from the smaller systems commonly found in light commercial applications to large-scale rooftop equipment weighing several thousand pounds. We can build support framing for 3, 5, 7.5, 10, 12.5, 15, 20 and 25-ton RTUs, as well as larger units when a project requires them. Whether you are replacing an existing rooftop unit or adding new equipment to a commercial building, we can fabricate the steel framing needed to support the specified load.
For standard light commercial buildings, we regularly accommodate the types of RTUs used on restaurants, retail spaces, offices and other commercial properties. Larger projects may involve 20-ton and 25-ton RTU support frames, multiple rooftop units, or substantially heavier equipment. We can also fabricate structural support systems for 25+ ton RTUs and large commercial rooftop units, including projects where multiple units need to be supported over existing steel trusses or other structural framing. If your project involves eight RTUs, a single large rooftop unit, or several smaller units distributed throughout a building, our Colorado welders can fabricate the support framing to match the equipment, roof structure and installation requirements.
Custom Fabrication of RTU Frames
At Top Peak Welding, we pride ourselves on our extensive experience in RTU support welding. Our Colorado Springs mobile welding team is equipped to handle a wide range of projects, from new installations to upgrades. Here’s how we approach each project to ensure the best results:

Thorough Site Assessment: Before installation, we conduct a comprehensive assessment of your building’s roof. For tall spaces like warehouses, we'll use a scissor lift to access and inspect the roof to determine the most effective support structure before beginning our work.
Expert Installation: Our skilled local welders ensure that 20 ton RTU curbs, or any other size, are securely installed and precisely aligned. We manage every aspect of the installation process, from welding to positioning, to ensure a stable and reliable support system for your heavy duty HVAC system.
Factors to Consider for Metal Roof Curbs
Selecting the right metal roof curbs or RTU support involves several key factors, including:
Unit Specifications: Provide us with detailed information about your RTU, such as its size and weight. This data allows us to design a custom RTU support that can handle the load effectively and safely without extra unnecessary material which can help you save on costs.
Roof Structure: The type and condition of your building’s roof play a significant role in determining the appropriate RTU support frame. Our team evaluates these factors to ensure that the support system is compatible and effective.
Local Regulations: Compliance with local building codes and regulations is crucial. We ensure that our commercial rooftop unit structural supports meet all necessary standards from Pueblo, to the Springs, and Denver.
