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:

Frame Features

Connection Clips - Specially fabricated clips are designed to securely connect structural components. Many companies supply only blank plates that must be cut, drilled and/or welded to components before assembly can begin. In some cases it may require many hours of work to connect required clips. Metal Building Depot details and supplies each clip and placement to every building manufactured. We factory weld all clips onto rigid frames and guarantee the correct placement of all component connections. Don't waste your time and money attaching clips that should have been factory located.

Structural Bracing - Most buildings under 60' have sufficient diaphragm action or "panel shear" that provides all the bracing needed to stabilize the building. In some cases of high winds, seismic or snow loads may cause more stress than panel shear can handle, so additional reinforcement may be required. In these extreme cases we will employ the use of X bracing to reinforce the frame. In situations where X bracing cannot be used a wind column is an excellent addition to strengthen a vertical rigid frame column. A portal frame is sometimes used in extreme load circumstances. Portal frames are fairly expensive and only necessary in rare circumstances.

ABOUT US

COMMITMENT - Our Company's vision is "to maintain a leading-edge in the design, engineering, fabrication and delivery of the highest quality steel buildings in the industry." We are deeply committed to providing you with this service as a means of achieving our vision.

VALUE - Low initial cost does not always provide the best value. It is just a small part of the picture. The values inherent in our designs assist in the ease of construction of the project but more importantly we provide a well-documented system that is easy to maintain. Much of the value we bring lies in the details. There is a true ART to engineering and design that provides added value to the Owner.

EXPERIENCE - With over 8 years in the manufacturing business and key staff members with many more years in engineering, we have the requisite experience. Major hardware and accessory suppliers have reviewed our capabilities and recognize us as leaders in our field. Many of our projects involve very difficult project constraints. Dealing with these issues and tight project schedules is the trademark of our success.

PROJECT METHODOLOGY - The success of a project lies in the talent of the design team and in the execution of the project. We first provide a strong project team, backed up with a well-defined and proven project execution methodology. Our project methodology has evolved over the years as we have executed numerous projects. It begins with our proposal document and extends through project documents, design sequence, system testing, acceptance documents and to the final delivery of our building system. The key to our methodology is communication. We strongly believe in defining what we are providing and expanding this initial definition as the project continues.

QUALITY - In engineering, quality relates to the designs we produce and the timing in project execution. Our goal for design is to provide a superior level of detail in documentation. We strive for uniformity of design, providing details often left out by others and keeping systems simple. The key to being on time is project execution. First, a well-defined project methodology is needed to set the planning framework. Second, understanding of the Owner's needs is paramount. Finally, our years of experience in the execution of critical projects have given us an essential edge over our competitors. Key members of our staff have up to thirty-five years of experience in project engineering and execution.

Roof Extensions and Overhangs

Extensions can improve the appearance of a building but will cost more. Roof extensions add "curb-appeal" to some buildings, but will take more time to complete the erection of the building because of the amount of extra covering trim. Extensions can also help a building merge in better in an environment of conventionally constructed buildings in commercial areas. An overhang offers you some protection from the rain and shade from the sun. These options can be important when you receive many visitors to your building, by offering shelter from the elements.

We offer two types of roof extensions: (1) Gable Extensions for endwalls (2) Eave Extensions for sidewalls. Using our system, you can easily and quickly design and price buildings with overhangs up to 5' on any or all of the walls. When in the Building Accessories section select Roof Extensions.

Recommended Installation Methods of Insulation

Roof insulation rolls are cut to lengths that will cover the distance from eave to eave, leaving a one-foot overhang on each side of the building.

1) Start at the end of the building and temporarily secure one end of the roll by attaching the insulation to the eave strut with double-faced tape.

2) Pull the insulation across the purlins with the vapor barrier toward the building interior. Double-faced tape attached to the opposite end of the insulation will keep tension on the roof roll while the metal panels are being attached over the insulation.

3) Install the next roll in the same manner, making sure the rolls are stretched tight, aligned properly and closely butted.

4) Fasten tabs using one of the methods described on the following page. Any rips or tears must be covered with matching facing tape to ensure a tight vapor seal.

5) Trim excess insulation flush to prevent it from acting as a wick and moving water into the building.
