Walk Doors

Walk doors can be provided as pre-assembled or knock down (field assembled). Metal Building Depot provides solid doors for both options in the following sizes: 3070, 4070, and 6070. The walk doors are typically keyed alike per project. Because of unknown variables, Metal Building Depot does not offer fire rated doors or doors to fit in masonry.

Features of the pre-assembled doors are as follows:

Foam insulated specifically designed for metal building use. Pre-assembled and self-framing for ease of installation. No framed opening required if Metal Building Depot standard girt spacing is utilized. Doors are finished in a two-coat primer; color selection is white or bronze. Doors are shipped in wood crates for protection. All doors have Grade 2 lever locks as standard. Hinges are ball bearing and powder coated. Insulated jambs. 3070 and 6070 doors are made of 20-gage material, 18 gage is available.

Features of the knock down doors are as follows:

Foam insulated specifically designed for metal building use. The walk door is shipped knocked down for field assembly. Doors are textured 20 gage galvanized prime painted and pre-finished in either white or bronze. Weather stripping and standard entrance lock is included. The walk door package is shipped with polybag and full cardboard carton. All doors have Grade 2 lever locks as standard. Hinges are ball bearing and powder coated.

Structural Framing

All frames are welded on a state-of-the-art computerized submerged welding system. We are capable of producing structural members up to 72" in depth, which gives us the ability to manufacture clear-span buildings up to 150 feet wide! A factory primer coating is applied to protect the beams during shipping and erection.

All framing members shall be shop fabricated for field bolted assembly unless otherwise noted on plans and specifications. All building parts shall carry an identifying mark for easy field identification. Structural framing shall include tapered beam frames, tapered rigid frames, modular beam and columns, lean-to rafters and columns, canopy beams, intermediate columns bearing end frames and end wall columns. Steel used in the fabrication of built-up primary structural members shall have a minimum yield of 50 KSI. Hot rolled primary structural members shall have a minimum yield of 50 KSI. Cold rolled structural members shall have a minimum yield of 55 KSI. Primary framing shall be shop fabricated and include all holes required for attachment of secondary members and bracing. A continuous arc-welding process shall join flanges and webs of built-up welded members. End wall columns and rafters shall be "hot-rolled" built-up "I" or standard "cee" sections.

Connections - All field connections shall be bolted. All primary bolted connections shall be furnished with high strength bolts conforming to A.S.T.M. A-325. All secondary bolted connections shall be furnished with machine bolts conforming to A.S.T.M.-A307.

Storage Buildings

It almost appears that almost every, home and garage is bursting at the seams. Surplus or unneeded equipment, furniture or other belongings clutter closets, attics and garages. But, the option of monthly storage fees does seem like a hefty price to pay just to hold on to the things you have.

Self-storage buildings are an easy way to put your money in someone else's pocket. Holiday decorations, childhood keepsakes and files all need to be retained for different reasons, but the cost of storage is a burden. Owning your own storage buildings is one way to lessen the expense of personal storage with a one-time quality investment.

The exciting thing about steel frame storage buildings is that you only buy them once. Mini storage is not as friendly you pay and pay, but you never own anything but the contents you placed in them. You may think that you don't need something as permanent as owning a personal storage building. But think about it - when are you going to let go of the things you have decided to save?

Wall Installation

Labels on wall insulation rolls indicate the length as well as the number of pieces that need to be cut from each roll. We recommend that all rolls be cut from a clean location to avoid staining the insulation facing.

1) Cut the dimensions of the insulation from the base angle to eave strut or rake plus 6"-12" extra.

2) Attach one end of the insulation to the base angle using double-faced tape.

3) Pull from the other end to stretch the insulation tightly outside the girts to the eave or rake, and attach with double-faced tape.

4) Make sure the facing is toward the interior of the building and attach the panel to the structure.

5) Install the next roll in the same manner, with edges butted snugly. Then fasten the tabs using one of the methods described.

Heat Transfer

Effectively controlling temperature in a steel building requires insulation to be present along exterior walls and roof. When a temperature differential is present in an enclosed steel building, heat will work from warmer areas to colder areas until the temperature in the building has stabilized. At the point of thermal stabilization, the cooler (and heavier) air will be present at lower elevations and warmer air will be present at the roofline. The function of insulation is to help stabilize air temperature at more desirable levels. When it is hot outside, preventing heat from transferring into the building is the goal, and of course in the winter we want heat to remain inside.

Heat transfer occurs in three ways:

Conduction : Occurs in a solid or liquid when heat from one object is transferred by touch to another object. An example of this occurs when a pot on a stove will heat up by conductive heat transfer from an electric coil.

Convection : Occurs with the physical movement of air. There are two types of convectional heat movement. The first is natural, where hot air rises displacing the cold air and moving it down. The second type is forced or mechanical convection. This occurs when an object, like a fan, physically moves or "forces" the air to move.

Radiation : Occurs when an object is warmer or hotter than the air around it. For example, the sun, which is hotter than everything around it, radiates heat waves that travel through the air and is either absorbed by or reflected by the surface it comes in contact with.
