Ridge Vent

Ridge vents come completely assembled for ease of installation. Ridge vents supplied by Metal Building Depot are of a low profile design to provide gravity type ventilation. Because gravity ridge vents are designed to allow free airflow, some penetration of water during blowing rains is to be expected. Standard available finishes for the ridge vents are polar white and galvalume. Other colors may be available at an additional cost. Nominal ridge vent length is 10'-0". Ridge vents are available with 9" and 12" throats. Bird screens are provided as a standard. The ridge vents can be ordered as continuous or single units. Exterior parts are 26 gage painted or galvalume. Interior parts are all made of G90 galvanized steel. The substructure consists of 10 gage saddle straps with interior baffles of 24 gage steel. Lifter arms and damper slides are made of 18 gage steel. Manual operation is through activation of a pull bar which is attached internally to bell cranked type lifter arms connected to the damper with Teflon coated pins through the damper slides. Dampers are spring loaded to remain in the open position until the pull bar is operated and locked in the closed position. Dampers operate in a vertical manner. Each vent is opened by a pull chain that extends approximately 12" below the roof unless noted otherwise on the order documents. Other opening mechanisms are available at an additional cost upon special request. Ridge vents should not be placed closer than 5’-0" to the endwall steel line to allow room to properly flash the building. For example, a 90’-0" long building with ridge vents required the entire length should have no more than (8) units. The ridge vents are available with the following accessories:

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.

Engineered Buildings

Don't be reluctant to purchase an engineered building because you think that it will limit your options. There are unlimited building styles and configurations to choose from. A person needing a metal church building will most likely want a different construction style than someone looking to erect a steel building horse barn. For this reason, engineered buildings are as diverse as the purposes they are used. If you require assistance in addressing your particular needs and specifications many steel building manufacturers offer design services to walk you through the process, some even offer online design programs.

Most pre engineered metal building manufacturers will have a common design that suits your needs, but never hesitate to ask for custom designed plans. A qualified manufacturer should make no hesitation in designing the exact building you desire.

Benifits of Steel Buildings

There are many benefits to building with steel over conventional construction methods. A steel building is probably one of the most economical building choices you can make. Steel buildings have many features not available with many other forms of construction. Steel buildings are typically more economical than conventional methods and can be completed in approximately two-thirds the time required for conventional construction. The appearance of steel buildings can easily be enhanced with many forms of exterior finishes. A suitably insulated metal building can drastically decrease heating and cooling expenses. Insulated roof and wall systems preserve and reassure thermal efficiencies. Extended life materials reduce maintenance, and eliminate troubles such as structural deterioration, rotting and insect damage.

Structural Design

We design and manufacture pre-engineered steel buildings, and offer you a number of advantages over conventional construction techniques. Steel buildings are inexpensive and incredibly tough. Our bolt-together design is assembled quickly without any specialized skills. Each rigid frame is comprised of two or more columns supporting a rafter across the width of the building. In most steel buildings, endwall bearing frames support one-half the load of a rigid "main" frame. In most situations, we utilize the more economical "bearing" end frames. Adding an expandable endwall or rigid frame is only a click away. Unlike any of our competitors, we allow you to choose the endwall condition of your building. Depending on design considerations, our endwall rafters and columns may be either hot rolled or cold-formed.

The space between the rigid frames of a steel building is referred to as a "bay."- an 80' long building has been divided into four 20' bays by spacing the frames 20' apart (4 x 20' = 80'). This configuration is described as "four bays at 20." A 100' building could be configured with four bays at 25 (4x 25' = 100')

Endwall bay spacing is usually determined by the building width. You can add one or more framed openings to most buildings. Endwall bay spacing can usually changed to accommodate your needs without changing the price.
