Von Gross Pole Building Construction

Engineered Footings

range from pre-cast concrete footing pads to custom poured concrete, set 5’ below grade. (Northern Minnesota Code)

Post Types range from solid sawn timbers to multi-ply engineered laminate columns. Posts and columns are treated to a minimum retention of .60 lbs. of CCA-C preservative per cubic foot of wood.

Post Spacing ranges from 6’ to 8’ on center. On center spacing flexibility allows

us to combine your building needs with the most economical and structurally sound design.

Truss Spacing range from 2’ to 8’ on center. Truss and post spacing are normally equal to each other in cold storage buildings. However, buildings that are going to be finished inside may have posts 6’ on center and trusses 2’, 4’, or 6’ on center depending on ceiling material type and other design criteria.

Wall Systems typically include a 6” non-arsenic treated grade board system with 1650# MSR (Machine Stress Rated) wall girts. MSR lumber is mechanically tested and graded for strength and integrity. 1650# MSR lumber is typically 2 grades or more higher than SPF Lumber which most lumber yards stock

Engineered Roof Systems include 1650# MSR purlins and engineered trusses

set on notched columns. Notching the columns allows the weight of the roof system to be directly transferred to the columns and footings. Standard trusses include an additional 7 lb. ceiling load for the safe installation of ceiling steel liner panel.

Ventilation design includes continuous ridge venting at the peak of the building and unobstructed ribs at both eves with a

minimum roof steel overhang of 6”. This unique design allows for maximum, non-mechanical, “free air movement” of fresh air into the building attic airspace at the eaves, and the escape of warm humid air out at the ridge, while effectively restricting rain and snow from entering the building.

Steel roofing and siding product is a 29 gauge, G60 panel with a 45 year

siliconized polyester paint warranty. Upgrade options include: G90, G100 26 gauge, and Kynar paint finish. Steel siding and roofing are fastened with gasket-mounted screws.

Roof-to-Eave Detail allows roof steel to extend beyond the eave wall approximately 6”. ROOF-TO-GABLE DETAIL includes steel corner trim to finish off the transition from the roof steel to the wall steel.

Ridge Cap is a 20” wide metal cap running the entire length of the peak. For cold storage buildings, polycarbonate ridge cap is a “clear as glass” economical lighting solution rated 20 times stronger than fiberglass.
