Overhead Doors - These 26 gauge roll-up doors come in a variety of colors with siliconized polyester paint over the primer coat. Magnum Steel offers a series of overhead doors to fit every need and all are available with or without automatic openers.

This series of doors is designed for everyday light duty use. It’s the perfect door for warehouse and manufacturing building projects, but is limited to a maximum size of 12’ x 18’. The doors come complete with all hardware 13-gauge saddle clamps, 10-gauge slide locks (2 per door), 16-gauge step plates (2 per door), and chain hoist with 4:1 reduction.

The 250 / 275 series is designed for frequent use and is a great door for every application from commercial usage to residential garages. All hardware is included with each door including 13-gauge saddle clamps, 10-gauge slide locks (2 per door), 16-gauge step plates (2 per door), and chain hoist with 4:1 reduction. Maximum size for the series 250 / 275 is 18’ x 18’.

This series is designed to meet the most stringent wind loads of Florida and in the Coastal Regions. The building codes in those areas require these overhead doors to be windload certified and come complete with wind-locks for stronger performances and all necessary hardware. These doors are limited to a maximum size of 16’ x 20’.

Series 650/651 is the premium door for mini storages with easy operation and maintenance. These doors feature shielded steel radial bearings on both support brackets. The tension bracket allows you to easily, quickly, and safely adjust tension on your door. With unlimited tensioning positions, the 650/651 door can be adjusted to the right amount of tension, avoiding service calls. This series is available in a variety of standard and custom sizes and includes 12-gauge door stops with slotted mounting holes, 14-gauge galvanized steel handles, 12-gauge coined tension bracket, and a 12-gauge bearing bracket.

Sliding Doors - They are available in both single and double slide versions, in widths ranging from 10' to 30' wide. Each door comes with a galvanized track and frame, to promote longevity and ease of operation. The nylon bottom door guide pad positioned at three locations along the base provides consistent operation. Sliding doors are available in two models, Model 835 and Model 837. Three options may be added to either door model for an additional charge.

Ø      Dual track configurations available to enable multiple doors to slide in
        one direction when side room is an issue
Ø      Keyed lock available to secure door
Ø      Doors can be divided into multiple doors to close the opening. Two
        inch lap on door edges required.

Rollers for Model 835 are four 1.4” diameter roller carriages designed for loads up to 400 pounds total door weight (2 carriages per door).

This door has the same features as the light duty model but uses a heavier track and rollers to handle doors up to 950 pounds each.

Hanger Doors - Magnum Steel can provide bi-fold, sliding, or stack doors to fit your pre-engineered airplane hangers' dimensions. There are two types of pre-engineered steel aviation buildings; corporate hangers and T-hangers. Corporate hangers look more like a typical steel building and use an open-end mainframe design to allow for a large slider door in the end wall. T-hangers are designed to store the maximum number of small airplanes in a "T" formation by dividing the building up into "T" units. Sliding doors or bi-fold doors are typically used for T-hangers. Corporate hangers do not utilize space as well as T-hangers, but are the more popular choice for our pre-engineered aviation buildings.

Dutch Doors - These doors are shipped completely assembled, in two pieces and this steel-clad, pre-hung door is a great maintenance-free exterior door. Available in a wide range of colors, these doors are ideal for letting plenty of light and ventilation into your stalls. The hardware kit (hinges, barn latch, door catch, barrel bolt, screws, and installation instructions) is included.

Materials: 16 gauge, one piece perimeter door panel frame is assembled over 29 gauge flat steel sheets. There is a pre-punched, 3-piece, 16 gauge jamb kit provided to assure a quick, accurate, sag-free installation of the door.

Dimensions: Each panel (2) is 48"W x 42"H x 1 3/8" T (Rough Opening: 49 1/2" x 87 3/8" (includes jamb)

Framed Openings – Factory located openings that may be used for all types and sizes of commercial entry ways, including storefront glass, sliding, Dutch, and overhead doors.

Walk Doors - They are pre-finished commercial white, with solid core insulation and complete hardware package. Optional hardware includes door closers, panic hardware, and mortis lock.

Note: It is possible that installing an unusual number of walk doors in a wall could compromise its structural integrity. Please advise us if you plan something out of the ordinary.

Gutters and Downspouts - Gutters really enhance the appearance of a building, and, except in areas with a lot of snowfall, we strongly recommend them for commercial properties. Gutters and downspouts control the runoff from the roof. They prevent it from splashing the sides of the building with water and mud, and they help channel it away from parking lots and other areas where you don't want water to pool. Magnum Steel provides factory-mitered rake and gutter trim, and our custom-manufactured corners are literally a snap to install properly.

Liner Panels – Interior walls of steel paneling that is excellent for finishing off the inside of your building. They are available in 26 & 29 gauge galvanized steel and are screwed into the wall and/or roof framing. Liner panels serve two purposes; they give the interior a finished look and they protect the insulation and exterior walls.

Eave Canopies and Roof Extensions - Many steel buildings use canopies and roof extensions because they can increase the performance for a relatively small additional cost. Canopies are similar to roof extensions, but a canopy creates an overhang on the sidewall, whereas a roof extension creates an overhang on the end wall. There are a number of benefits to both canopies and roof extensions.

Skylights & Wall Lights - These translucent panels provide inexpensive lighting through the roof and the walls. Optional insulated skylights are also available.

A "light transmitting panel" is a plastic roof panel installed to admit light. The UV-stabilized, light transmitting panels are high strength translucent panels that are made of glass fiber reinforced polyester. The high strength translucent panels match standard panel profiles, and are white with a granitized top surface. Insulated light transmitting panels are also available.

Windows - These windows are self-framing and flashing. We offer them with single or double pane in a wide variety of sizes. Optional Thermal glass is available as well.

Magnum Steel offers several types and sizes of windows for metal buildings, including two sizes of insulated windows and two "slimline" sizes. Each package includes aluminum window frames, glass, and flashing fins. More detailed descriptions and specifications follow.

Magnum Steel’s windows are "field located," meaning that we do not include them in the design of your steel building. You can install them on any section of a wall that is not obstructed by a column or bracing cables. If the precise location of one or more windows is critical, you should confirm the exact column and cable placements.

All of our windows are "self flashing." They include fins that match the profile of the wall panel and attach to it with screws. Typically, no other framing is needed; however, some special situations require a full subframe with sill, header, and jambs. Magnum Steel adds a framing kit to windows selected for buildings designed with a wind load of 100mph or greater. With lower wind loads, these same kits are available as an option.

Note: It is possible that installing an unusual number of windows in a wall could compromise its structural integrity. Please advise us if you plan something out of the ordinary.

Sizes marked with a * are available both insulated and non-insulated. Non-insulated models have mill-finished (aluminum) frames and insulated models have a bronze finish. The "nominal" dimensions below include framing and flashing. To figure the size of the opening needed for a window, use the formula (Nominal Width - 2 1/8”) x (Nominal Height + 1/2”).

Horizontal Slide (½ screen)	Single Hung (½ screen)	Slim Line
Clear DSB glass (non-insulated) 5/8" SSB glass (insulated)	Clear DSB glass	Gray-tinted, Tempered
3020 (3'x2') * 3030 (3'x3') 4030 (4'x3') 6020 (6'x2') * 6030 (6'x3') 6040 (6'x4')	3030 (3'x3') 3040 (3'x4') 3050 (3'x5')	1070 (1'x7') 2070 (2'x7')

Door Canopies - A projecting roof system that is supported and restrained at one end only. These low profile canopies are available for both 3070 and 6070 walk doors and a variety of other custom sizes and styles. Ideal for added shade a protection from weather conditions over windows as well.

Circular Vents - Ventilation is important in steel buildings and the most economical way to vent your building is a circular vent; comes in 20” and 24” models with corrugated or flat flashing and complete with operator. Each vent includes a bird screen and features a spring-loaded butterfly damper which locks securely open until released. Our flat-base vents can easily be field modified to fit the appropriate roof slope for a weather tight installation.

Ridge Vents - Available in 10' sections, the 26-gauge structural-quality galvalume vents are available in mill finish or Polar White to really pull the air through your building, with or without operators. For a typical steel building, one 10' ridge ventilator will serve 2400 square feet of space. Each comes with rain cap, bird screen, and an adjustable damper as well as the connector bar and gutter splices needed for installing multiple units in a continuous run. The base is preformed to the proper roof pitch (1:12 up to 4:12), and we provide instructions for their simple installation.

Louvers - They can be fixed or operable, and they allow you to put fresh

air into your building. An insect screen is standard, and louvers may be installed either singly or side-by-side. Available in standard rectangle or custom shapes.

Note: Like windows and walk doors, louvers can be placed on any unobstructed section of a wall. If the precise location of louvers is important, call and discuss it with one of our representatives before you buy a building or as soon as possible afterwards.

Cupola - An outlet for the natural flow of warm air in an upward direction is provided through the louvered sides of this cupola, while adding charm to the appearance of your steel building. Available in 2, 3, and 4 foot square models, our fully functional cupolas are constructed of 29 gauge steel and are available in a wide variety of colors to match your building. The cupola comes with a bird screen and color coordinated flashings, and is available with either light transmitting panels (Plexiglas) or vents.

We offer a complete line of weathervanes to give your cupola that finishing touch. The weathervanes come in two sizes - 30” for two and three foot cupolas, 40” for the four foot cupola. They are constructed of high cast aluminum, painted in black, and are available in six different designs; horse (shown above), tractor, horse and buggy, rooster, cow, or eagle.

Insulation - Fiberglass is an excellent insulator and has been widely used in the United States for decades in all types of construction. Although fiberglass insulation is available in many forms, we recommend that you only install a product that has been specifically designed for use in steel buildings. Steel building insulation consists of blankets of woven long-strand fiberglass that are laminated on one side to a vapor-barrier facing. We use only "UL" rated insulation of the highest "R" value, available with vinyl or reinforced backings. Below is a listing of the accepted R-values for fiberglass blanket insulation of different thicknesses when properly installed in metal buildings (higher numbers indicate greater effectiveness).

3".....	R-10
4".....	R-13
6".....	R-19

The facing material of metal building insulation plays several important roles. Different facings vary in three key qualities: workability, permeability, and durability.

The workability of a facing refers to the temperature conditions required for installation. Cold causes some vinyl facings to become brittle, and these may crack or split during installation. Not only does this kind of damage look bad, but it will seriously degrade the facing's ability to do its job as a vapor barrier.

The permeability of a facing refers to the rate at which water vapor will pass through it. Metal buildings need a good vapor barrier. The effectiveness of various materials is measured in "perms," and lower numbers mean greater resistance to moisture. Most facings are layered with different materials, and the better ones usually incorporate polypropylene or some other essentially waterproof material.

The durability of a facing indicates how well it stands up to physical stress without ripping or tearing, which is important because the facing is usually left exposed on the interior of a metal building. The least durable facings are made of one layer of un-reinforced vinyl, which can be punctured or damaged by only light contact. Reinforced facings have a layer of "scrim" or some combination of materials that help prevent the facing from tearing.
