Specifications

Metal Building Framing Details are International Accreditation Service (IAS) accredited

A steel building system consists of many significant members. If a few or possibly even one member is missing, miscut, or designed incorrectly, delays and added construction costs could occur. Therefore, it is wise choice to buy from an IAS accredited manufacturer.

The key feature of a rigid frame metal building structure is the I-beam mainframes. The material used is 50,000 p.s.i. yield strength (Some manufacturers use only 34,000 p.s.i. yield strength material). Frames are single bead, continuous submerged arc welded by automatic welding machines to help ensure quality. Factory-applied rust-inhibiting primer is used to help protect the mainframes and secondary material during the erection process.

Wall girts, roof purlins, and eave struts are considered secondary members. These members do not carry much of the overall loads; however, they support the walls and roof panels. In addition to this, they transfer loads to the frames and help stabilize the building. 

GIRTS SPECIFICATIONS (in the sidewall) and PURLINS (in the roof) are a minimum of 8” to 10” to meet design requirements. Cold rolled Z-section, 12 to 16 ga, 57,000 p.s.i. yield material is used to provide maximum strength.

The bypass girt system overlaps at sidewall columns forming a continuous “span” for extra strength. All girt clips are factory welded for easier erection.

In order for a building to handle the stresses such as torsion, lift, compression and shear, it must have some form of bracing. The primary bracing utilized by steel buildings are X BRACING, FLANGE BRACING, DIAPHRAM BRACING, WIND COLULMS, and PORTAL FRAME.

X bracing uses steel rods or cables that extend diagonally from frame to frame. They keep the building tightly connected. All diagonal galvanized cable bracing is supplied for the roof and walls to remove longitudinal load from the structure. All cables are pre-stressed and pre-made for easier erection.

Diaphragm bracing stems from wall and roof sheeting. The sheeting acts like a “securing force” keeping everything together.

Angle Flange Bracing is provided for the connection of the rigid frame to the purlins and girts. This ensures the allowable compressions are adequate for any combination of loading.

To reinforce a column, a wind column is used.

A portal frame is columns placed within a bay (vertically and horizontally) in lieu of X bracing.

Canopies– are optional on the sidewalls

Purlin Extensions– are optional on the end walls

These are the most common items added to orders, simply because they enhance the building’s appearance and performance. The additional cost is minimal -with purlin extensions less costing than canopies. Our extensions are 1’ to 5’ and a soffit is a standard feature.

DEEPER HIGH-RIB SHEETING 26 gauge (1 ¼” PBR), 80,000 P.S.I. yield strength material with more frequent corrugations that provides extra strength than an R profile as well as has a larger overlap. Some firms use an R panel for their roof sheets (picture on right).  Most pole barns and tube buildings use a lighter 29-gauge sheeting thickness.   Some manufacturers use a lower yield strength material, which is less resistant to damage from hail or other impacts.

Rib Spacing: 12” on center. Coverage 36”.

Quality Product Details Numerous UL 580 ratings are available, as well as UL 790, Class A for external fire, roof assembly for UL 263 for internal fire, and the UL 2218 Class 4 impact rating. PBR carries Florida approval, Dade County ratings, and FM 4471 approval standard for Class 1 panel roofs.

(29 or 26 gauge) are a standard 3’ wide panel that screws into the framing. They run the entire building or to the eave height or to the standard 7’4” girt. A connection point at the base is required when you order liner panels. Your liner panel will enhance your building’s appearance as well as protect the interior wall and any insulation.

Many times, the first thing one notices is the trim because its purpose is to highlight a building. Needless to say, poor-looking trim makes the building look cheap and ragged, wherein nice sculptured trim will make your building look finished and professional. Your trim accomplishes two things: It connects the transition areas which helps seal the building and protect it from moisture. Unfortunately, many companies save money by simply supplying generic trim that has to be field located to fit.  This compromises the integrity of the building as well as they look. Factory Steel Overstock offers a sculptured trim specifically designed to fit your structure. The snug fit makes the erection process easy and you experience many years of durability.

Some consider the gutters and downs an accessory; however, they perform some of the same functions as the trim. Not only do they enhance your building’s appearance, they also control the rain runoff. Factory Steel Overstock offers a standard gutter & downs for low snow areas and a stronger design for heavier snow areas. In areas of high snow, we don’t recommend gutters and downs.

40-year warranty on premium color finish on walls and trim. The roof finish is Galvalume Plus or premium colored finish. Galvalume Plus roof warranty is 30 years.

ALL COIL STEEL has a minimum Galvalume substrate to help prevent deterioration of the steel sheeting.

Have cold-formed C-section jambs and headers to help ensure easy installation of overhead doors, etc. Framed openings large enough for a car to drive in, require anchors to the concrete. In order to increase profits, many sellers offer only “field located” framed openings. However, this action means the customer must carefully cut into the steel members at the job site without directions. Other than walk door or window openings, we suggest the manufacturer always design and frame the openings.  With Factory Steel Overstock, the general public will always receive these large “factory-located” framed openings that are FULLY FLASHED!  This means the attractive openings will be shown in the certified plans as well as the parts will be precisely pre-cut and labeled. The significance of this is each metal building system is designed to withstand the demands and stresses of the different openings put on the design.

Your base condition determines provides a lower connection for your wall panels as well as how the panels relate to the wall panels. Below are the common 4 base conditions:

Standard base angle – The base angle is to be attached to the concrete with ram-sets or equivalent anchors. However, this base condition requires that the slap be formed with a 1” sheeting notch. This notch increases the concrete cost; therefore, we believe a better investment is to simply order a different based option.

Formed base trim – If you want to finish off your building nicely, simply request Formed base trim.  This attractive item also seals the bottom of the building more effectively than the foam closures. Unwanted creators may penetrate through the foam, but they won’t be able to get through our sturdy formed base trim!

LONG OVERLAP to help prevent water from siphoning into buildings. Factory Steel Overstock offers die-cast ridge caps that connect the roof panels. The ridge cap covers the peak. Some sellers offer ridge rolls that are bent in the field and sealed with closures. Moreover, fitting them is difficult and over time they may deteriorate enables birds to nest in that area. Rest assured, our ridge caps match the panel profile and the roof profile; therefore, leaving no area leaks or pests.
