Accusteel Frames
The Lark AccuSteel frame building is the biggest advancement in portable building design and construction in the last 40 years. Lark manufactures the AccuSteel using one of the most precise and advanced roll-forming systems available. The strength, quality, and durability of this steel frame system are truly awesome. The AccuSteel is manufactured using a totally new concept of roll-forming and assembly. A system and method of steel stud construction that is unprecedented. Lark manufactures the AccuSteel building using a state of the art computerized roll-former and software system. The frame of the AccuSteel is roll-formed from heavy duty 18 gauge G-90 galvanized material that not only give you superior strength and durability, but also provides needed rust protection.
If you are interested in a portable building, you owe it to yourself to critically evaluate this new high tech building system. See why we are sure you will agree that strength, quality, and value like this does not come along every day.
Great Reasons to Buy an Accusteel Building
- Steel does not warp, split, crack or creak;
- Steel has the highest strength to weight ratio of any building material;
- Steel is not vulnerable to termites or any type of organism;
- Steel does not burn or add fuel to the spread of fire;
- Steel has less probability of damage in high winds, stronger connections (screwed vs. nailed);
- Steel is dimensionally stable; it does not expand or contract with moisture content.
- Steel produces less scrap and waste (2% for steel vs. 20% for wood);
- Steel is environmentally friendly — 100% recyclable, saving landfill space.
Vertical Galvalume Roof
A roof is designed to keep water out. In the metal building industry, Lark has surpassed the others in roof design to not only keep water out, but to KEEP the building from leaks for the lifetime of their building. Other manufacturers lay aluminum lap siding (the material that is on the outside walls of their building) on the roof horizontally. This saves the manufacturer time and money. Unfortunately, these applications are prone to leaks because the water does not channel off of the roof effectively. Lark, however, builds a roof with longevity in mind and does it the RIGHT way. They use a break to bend the sheet of metal over the peak, eliminating a seam and allowing the water to channel off of the roof. They also use galvalume instead of aluminum like our competition to resist punctures and keep the building cooler with a silver, reflective finish. Finally, because our roofs are screwed into steel trusses, it insures that the screws do not back out over time like in wooden frame construction.
NO ONE BUILDS A FLOOR LIKE LARK!
Now with galvanized steel floor joists and perimeter!
Floor Skid Fabrication
While other manufacturers use two 2 x 6′s nailed together for the all important base structure or floor skids of their buildings, we at Lark use only solid 4 x 6′s that are precision trimmed, tapered, and dadoed for our floor skids. When we require skids that are longer than our available timbers, we mortise the splice and make the connection using six 4″ galvanized lag bolts. This assures the uncompromising strength and durability of our buildings.
Floor Frame Assembly
All of our floor joists are connected to the skids by being nailed and lag bolted at each dado to assure that the base of our buildings have superior wind uplift protection. On the skid ends, we not only double lag bolt our headers at a 45 degree angle to the skids, we also hurricane clip them for additional holding power.
Plywood Installation
One of the most outstanding features of our Lark floor system is the way we connect our 23/32 treated plywood to our floor cross members. We don’t use nails that can back out and weaken the floor. We use only plated deck screws that give the floor more strength and rigidity than nails. When we place this 23/32 panel on 16” centers we are able to give you a floor loading of 125 P.S.F. The reason we use this floor loading is to insure that the superior structure of the building is adequately supported and that the integrity and stability of the Unit is not compromised.
