Steel Dog Structures is a Colorado general contractor that handles your entire build in-house — steel procurement, erection, concrete, site work, even the septic system. One contractor, one standard of quality, no finger-pointing between subs.
Most steel building projects involve four or five different companies — and four or five chances for something to fall through the cracks. We self-perform the critical trades, which means tighter schedules, accountable quality, and one phone number for your entire project.
From the first site walk to the final inspection, we manage the whole project under our Class A & Class B Colorado licenses — design coordination, permitting support, scheduling, and every trade in between.
General Contractor Explore steel buildings →We buy your building direct from the manufacturers — I-beam rigid frame, cold-form, or insulated metal panel systems — spec’d correctly for Colorado wind and snow loads, at contractor pricing.
In-House Steel erection services →Our own crews assemble your structure — anchor bolts, primary and secondary framing, panels, trim, mezzanines, and stairs. Safe, square, and on schedule, with no erection sub markup.
In-House Steel erection services →Engineered slabs, foundations, and equipment pads designed for Colorado frost depth and soil conditions — poured by the same company that erects on top of them. Level, square, built to last.
In-House Concrete & site work →Grading, excavation, drainage, utility trenching, and access — we prep your ground so the foundation and building go in right the first time, even on rough or remote Colorado parcels.
In-House Concrete & site work →Building outside city services? We design and install onsite wastewater (septic) systems as part of your project — one less contractor to find, schedule, and coordinate yourself.
In-House Concrete & site work →Most people have never been through a construction project. Here’s exactly what happens, step by step — no jargon, no assumptions. Click any step to learn more.
