Serving California, Mississippi, and Texas, Simpson Steel Building Company supplies pre-engineered kits that make owning a steel building in California straightforward from quote to delivery. Whether you’re expanding a farm, adding storage, or launching a new shop, our metal building options arrive ready for efficient assembly, dependable performance, and long service life. We keep the process clear, flexible, and on schedule.
Engineered for Performance
Our kits include engineered framing, wall and roof sheeting, trim, and fasteners—everything you need to erect a professional-grade metal building. We offer practical accessories, coordinated shipping, and responsive guidance so your site, crew, and timeline stay aligned. Because we are a manufacturer—not a design firm—you can request minor adjustments and structural tweaks within our standards, then build with confidence.
A pre-engineered steel building saves time and reduces jobsite variables. You get components that fit, documentation that supports code review, and a project plan that respects your budget. Our patented truss system focuses on value and constructability, helping Mississippi owners get a durable metal building without unnecessary complexity.
Scope and Fit
To ensure reliable installs, our truss buildings are limited to 50′ width, 18′ eave height, and non-extreme snow or wind conditions. Need something outside those limits? Ask about alternative frames that can address larger spans or higher design loads. Either way, you’ll receive straight talk, realistic schedules, and an experienced team that supports you before, during, and after delivery. Ready to move from idea to order?

Simpson Steel Building Company has been providing metal buildings to the great state of Mississippi for over 40 years. We’ve become very familiar with and kept up with local building code changes that have come up over the years. Our patented truss design gives you all the benefits of a traditional red-iron structure for a much lower price point!
Steel buildings in Mississippi must be designed to be strong enough to handle a very wide range of climates throughout the state. Simpson’s steel building kits are prepared to handle the lighter wind loads in or around Oxford, Tupelo, Starkville, Meridian, Vicksburg, and Jackson, up to the heavier wind loads as you approach the coast in areas such as Laurel, Hattiesburg, Biloxi, Natchez, and Gulfport. Simpson can provide complete engineered plans, engineered design calculations, and engineered foundation plans that are stamped by a licensed Mississippi engineer in the event you need these items for permitting. Our building kits have never been denied a permit in the state of Mississippi.
Our bolt-together building kits are easy to assemble and only require a forklift or tractor with tongs to move around. This makes our building kit the perfect solution for any Mississippians looking for an affordable DIY Kit for their project needs. Speaking of projects, our buildings work great for a multitude of uses, such as hay barns, stables, garages, shops, commercial buildings, and barndominium homes! In the event that you want someone to erect the building for you, we have a list of local contractors we can refer to help with that aspect of the project.

Frequently Asked Questions
How do I prepare my site before the kit arrives?
Plan a level, compacted foundation with proper drainage and vehicle access, and confirm anchor bolt layouts if required by your engineer. Clear staging space for bundles, equipment, and safe travel paths. A prepared site shortens crane time, reduces rework, and helps you hit target erection dates.
Who unloads the delivery, and what equipment is needed?
You, or your contractor, are responsible for unloading at the jobsite. We’ll share estimated weights, bundle counts, and handling notes so you can stage forklifts, telehandlers, or a crane as needed. Proper rigging, a clear laydown area, and a spotter keep unloading safe, efficient, and organized.
What permitting and documentation should I expect?
Local authorities have final say, so start with your jurisdiction’s requirements. We can provide project drawings and, when requested, stamped documents to support review, while you or your contractor handles permit applications, inspections, and fees. Aligning submittals early helps avoid delays, unexpected revisions, and schedule pressure.
