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:

Foundations

Do I need a foundation for my metal building? - Some people choose to pour a full slab foundation, however if you're planning on leaving the floor in a dirt or gravel condition, concrete piers will do the job just fine. Please contact a customer service representative if you don't plan to pour a full slab foundation.

Can you provide an engineer stamped foundation layout? - Yes, but in some cases your soil conditions play a major role in the type of foundation you can use. Contact our special sales department for more information. If using a local engineer, we will provide anchor bolt plans to aid your engineer in designing the foundation.

Do you supply the hardware to attach the frame to foundation? - No, the anchor bolts are usually supplied by a concrete contractor and placed when the foundation is poured.

Erectors

Do I need a professional erector to put up my metal building? - A majority of our clients choose to erect the metal buildings themselves. Your package includes detailed erection drawings and an erection manual with every metal building shipped. We design every metal building to be erected easily. If you do not feel comfortable erecting your own metal building, a local contractor can do the job for you at a relatively low cost.

What if I have questions during the erection of my metal building? - We're here to help. We have professional metal building erectors on-staff and they will always be available for your questions.

Do you recommend erectors? - No. Recommending metal building erectors is difficult because we cannot guarantee the quality of their work as we do our own. Check around and you should be able to find a qualified metal building erector in your local area.

How long does it take to erect a metal building? - The time it takes to erect your metal building will depend on the size of the metal building, the size of your crew, and the skill of the workers in your crew. It can take as little as a few days.
