We also offer quality, durable steel building components - steel building parts and equipment that are highly specialized to provide maximum strength and be cost efficient. The combination of quality construction and affordability makes our steel building accessories and steel building replacement parts an exceptional value.

Base Conditions

At MBMI, you’ll find everything needed for fast and effective installation of your steel structure. Our selection includes base trims, base girts, base angles, base channels and more.

Formed Base Trim

Formed base trim comes standard on our buildings and will make installing wall panels very easy even without a notched foundation. This trim will allow you to save money on the foundation while saving time installing wall panels. Formed base trim also seals the bottom of the building better than the foam closure strips that most of our competition uses. Pests and weathering may be able to wear through foam, but they surely wont damage our 26ga formed base trim. The color can match the rest of the trim or wall panels and come standard with our industry leading 40yr Warranty.

Standard Base Angle

MBMI's standard base angle is 4" x 3". Most of our competitors use a flimsy 1" x 2" angle. When you use a base angle that is too small, the concrete is likely to chip or break because the fasteners end up being too close to the edge of the slab. This is why we use an oversized 4" x 3" angle, standard on all of our steel buildings. This is just another example of why an MBMI building is far superior to the competition.

Base Girt

Base girts are used for buildings without slab or perimeter foundations. Since there is no way to anchor an angle directly to the ground, a girt 3" above the finished floor is used instead.

Base Channel

Base channels are used with liner panels or are optional with stem walls. When used with liner panels, the inside of the base channel is used to attach the bottom of the liner panel. Base channel can be used with a stem wall if the wall is not poured solid with concrete. If a stem wall is hollow, you will not be able to use our standard base angle and you will need to opt for this base channel.

Rigid Frame System

We are committed to ensuring you can create or maintain steel structures at your home or business. Our selection of frame systems includes clearspan frames, multispan frames, single-slope frames and lean-tos.

Rigid frame clearspan - RF system

The rigid clearspan frame is the most popular design for MBMI Steel Buildings. This frame offers you incredible strength, durability, versatility and economy. The RF System offers the most practical solution to most ordinary clearspan building requirements from 20' through 200'. Our in-house engineering staff has years of experience designing these frames as efficient as possible to give you incredible strength at an economical price.

Rigid frame multispan - RFMS system

The rigid frame multispan system offers the most economical cost per square foot coverage with spans over 80' wide and interior column supports are not objectionable. Spans of over 400' wide are attainable with multiple interior columns. This frame system is great for large buildings including warehouses, distribution facilities, agricultural applications and even industrial buildings.

Single slope frames - SS system

The single slope system offers a wide range of uses from shopping centers, to large office complexes. Together with fascia systems and parapet walls, exquisite building lines can be achieved for a pleasing architectural treatment. The SS System may also be used as a wing unit, or as an addition to an existing building. This frame system can be combined with interior columns for economic large spans.

Lean-to

Lean to frame is designed to attach to main rigid frames or to any structure designed to support the additional load. These frames are very popular when customers want to expand on their existing building. These can be designed as a roof only system or completely enclosed.

Secondary Framing

This encompasses the girts, purlins, bracing and various angles. Sizes and material thickness is custom designed for your needs and to meet all building load requirements. All exterior sheeting is fastened to the secondary framing.

X Bracing

X-Bracing is used in buildings to provide additional bracing and strength. X-bracing is very economical and the most common bracing system MBMI offers. Bracing design depends on the steel building size and the local county loads. Our design engineers create a bracing system that is economical, yet very strong. This can be accomplished with steel cables, solid rods or even steel angle in severe cases.

Wind Columns

Wind columns are used when x-bracing causes an interference with openings in a particular wall. Whether there are doors, windows or open walls, wind columns are an economical substitute for standard x-bracing. A wind column is basically an "I" beam that bolts to the rigid frame and the foundation to provide strength and rigidity.

Portal Frames

Portal frames are used when you have the same situation as a wind column, but a wind column does not provide enough support. These frames are usually used on larger buildings and steel buildings with very high snow or wind loads. When x-bracing is not allowed in a wall and a wind column is not strong enough, a portal frame is used. Portal frames are very heavy frames that connect two rigid frames and increase the lateral support greatly.

Welded Clips

All of our girt and purlin clips are factory welded on all structural steel. Some of our competition uses bolted clips on the structural steel which take longer to install and are not as strong as a welded clip. MBMI uses welded clips to save you time and money when erecting your metal building.

Endwall Framing

Endwall framing can be designed many different ways. Endwalls can be built with C-channel, welded I-beams and even rigid frames depending on the situation. Endwalls can be designed to be closed or open depending on your application. The strength of the endwall components depends on the size and loads of the steel building. Our engineering staff can design the perfect endwall for your needs.

Girts

These steel members span the length of the building between frame lines on the walls. The wall panels are fastened to these members and provide the strength and framework of the walls. Girts are pre-punched "Z" shaped with a yield strength of 55,000psi and fabricated in 12, 14, and 16 gauge depending on the building loads. If your application calls for a spandrel beam, MBMI can supply heavy channel or I-beam sections. MBMI girts are bolted to the welded clips without any welding or cutting. They are coated with a durable primer that will protect the steel from rust and corrosion.

Purlins

These steel members span the length of the building between frame lines on the roof. The roof panels are fastened to these members and provide the strength and framework of the roof. Purlins are pre-punched "Z" shaped with a yield strength of 55,000psi and fabricated in 12, 14, and 16 gauge depending on the building loads. MBMI purlins are bolted to the welded clips without any welding or cutting. They are coated with a durable primer that will protect the steel from rust and corrosion.

Eave Strut

These steel members span the length of the building between frame lines on the roof at the eaves of the building. Eave Struts are pre-punched "C" shaped with a yield strength of 55,000psi and fabricated in 12, 14, and 16 gauge depending on the building loads. MBMI eave struts are bolted to the rigid frames without any welding or cutting. They are coated with a durable primer that will protect the steel from rust and corrosion.

Roof Extension

Roof extension can be added to any building and to any wall. Roof extensions can follow the roof line or can be designed below the roof. Roof canopies are great at providing covered area without any columns. This is the most economical way to keep the sun, rain and snow off the wall of a building and to cover openings or walkways. MBMI extensions are available with & without soffit panels depending on the look you want.

Screw down & standing seam roof

Choose between our standing seam and screw down roof options. Both roofs provide excellent quality for your building. See which option is best suited for you and your needs.

Screw Down

Screw-down metal roofing is a particular metal roof held together with screws that hold the roof securely. Individual screws are used to ensure the rigid metal roof is fastened to the structure. It is the most basic metal roofing system.

Standing Seam

Standing seam metal roofs are interlocked within each panel and are not fastened by screws. Depending on the aesthetic you prefer, you can choose standing seam sizes that are between 12 to 24 inches wide depending on the panel type. Fastening is accomplished through a 1-inch bend that enables interlocking. Without breaking tight seals, fastening allows the standing seam roofing to move and expand. By using a clip or nail flange system, the fastening on the metal panel is hidden below the surface of the panel . A hidden system is a huge advantage by eliminating the faulty or improperly fastened exposed systems.
