Cold-Formed Structures

Cold-Formed Structures

Over the years, many of our customers researching smaller-sized buildings (say, a 30’ wide home garage or workshop or a 50’ wide barndominium) have asked us for a product that offers the same great commercial-grade finishes of our welded-frame buildings, but at a lower cost per square foot with easy, DIY installation.  Tall order indeed!  So, we tinkered (as usual…) for a while and worked with our in-house engineers to develop a product that fit the bill perfectly.  We’re now proud to offer our very own cold-formed buildings in sizes up to 80’ with each and every structure capable of meeting the same code and load requirements as our welded-frame buildings.  Over 90% of the components in these buildings are roll-formed to ensure incredibly consistent profiles and fitment, and each cut and punch is laser-measured by our advanced production equipment.  Even better still, our cold-formed buildings come standard with all-galvanized framing for high-durability rust protection. Requiring no welding at all, these buildings install easily in the field using high-quality bolts and self-tapping fasteners.  After all that tinkering, our design engineers didn’t even ask for a raise, so we’re able to offer these innovative buildings to you at a lower cost per square foot than our welded frame buildings.  Mission accomplished.

All our buildings come standard with 26ga exterior wall sheeting and trim, specially coated with a siliconized polyester baked on finish to stand up to years of heavy-duty use.  Our standard “PBR” (purlin-bearing rib) profile is designed with an elongated overlap from panel-to-panel and comes with extra-tacky butyl tape to create a tight seal.  All our fasteners are stainless steel capped, painted to color-match your wall and roof sheeting.

Ostro provides a full set of drawings with each building, stamped by a professional engineer licensed in your state.  Pairing these drawings with our easy-to-read assembly instructions makes installation of your Ostro Steel Structures cold-form building a breeze—no onsite cutting, welding or punching.

Ostro Steel Structures Cold-Formed Buildings vs. The Competition

 

The Competition

Mainframes Cold-Formed Heavy Gauge Steel (10-16ga.) Lighter-gauge steel stud system providing lower durability and strength
Exterior Sheeting Profile “PBR” profile with extended overlap from panel-to-panel and butyl tape seal to keep water out Thinner 29ga “R” panel without extended overlap or sealant, allowing water to pass through
Roof Sheeting Coating Standard Akzo-Nobel® Galvalume® AZ55 coating combining zinc and aluminum to enhance longevity and rust protection dramatically. Standard 40-year rust perforation limited warranty. Basic coating with inferior longevity
Wall Sheeting Coating Galvalume® AZ50 substrate with siliconized polyester baked on paint with 40-year limited warranty against peeling/blistering and a 30-year limited warranty against fading/chalking. Basic coating with basic 10-year warranty
Framed Opening Header Trim Standard Ostro “Deep Well” water rejection profile at header to force water away from structure Basic “J” profile must be shaped during installation and allows ingress of water over time
Framed Opening Jamb Cover Standard on all framed openings, this color-matched trim hides the framing system from view Trim not included or costs extra
Base Angle Minimum 16ga. concealed fastener deluxe base angle Lighter-duty 18ga. angle with dangerous protruding screw points
Fasteners Stainless Steel-Capped with limited lifetime warranty Zinc-Capped without limited lifetime warranty
Foundation Plan Standard with every building Not included and often not offered

Top-Notch Warranties for a Top-Notch Building

 

Welded Frame Competitors

60-Year limited structural warranty guarantees your Ostro building will meet the snow, wind and seismic load requirements specified Many companies don’t offer this type of warranty at all.  Those who do typically offer between 30 and 50 years.
40-Year limited rust-through / perforation warranty on the AZ55 Galalume® coatings applied to your wall and roof panels Many companies use inferior steel mill “seconds” (panels that don’t meet intended specs) and don’t offer a warranty at all.  Those who do typically state 25 years.
40-Year limited paint coating warranty against cracking or peeling Many companies use inferior steel mill “seconds” (panels that don’t meet intended specs) and don’t offer a warranty at all.  Those who do typically state 20-25 years.
30-Year limited paint coating warranty against chaulking or discoloration Many—if not most—companies don’t offer this warranty at all.  Those who do typically state 25 years.
Limited lifetime warranty on all stainless steel capped fasteners Companies using ZAC-type zinc fasteners carry a short-duration warranty or none at all.
