Why Choose a Highwall Model (Lumberjack)?
By purchasing a Highwall Model you are getting an additional 1.5 feet of ceiling height for a total height of 8 feet. These models are a great option to add your shelving or taller items and will provide much more headroom for storage. The high wall models do not come in a barn style due to the DOT height laws governing transportation. Many people go for this option if they plan to use the portable building as a workshop and the cost to add the additional height is minimal given the price between a standard size and highwall model.
All models are customizable in size and options include door and door sizes, window and windows sizes, receptacles, and lights. These buildings will be anchored and rated for 180 MPH wind gust.
Floor assembly, Fabrication & Installation
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 has superior wind uplift protection. On the skid ends, we not only double lag bolt our headers at a 45-degree angle to the skids, but we also hurricane clip them for additional holding power.
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 ensure that the superstructure of the building is adequately supported and that the integrity and stability of the Unit is not compromised.

Accusteel Frame Buildings
The Lark Accu-Steel frame building is the biggest advancement in portable building design and construction in the last 40 years. We manufacture the Accu-Steel 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 Accu-Steel is manufactured using a totally new concept of roll forming and assembly. A system and method of steel stud construction that is unprecedented.
For years, steel stud construction has utilized a system of U-channels for the top and bottom plates and C-channels for the studs. When using this system, the U-channels and studs have to be measured and marked for center placement. This system lends itself to mistakes in measuring and stud placement. Using this archaic method of fabrication and assembly compromises the accuracy and quality of the finished product.
We manufactured the Accu-Steel building using a state of the art computerized roll former and software system. This system utilizes C-channels for all structural components, the top, and bottom plates as well as the wall studs. This amazing system measures and notches the C-channel for precise stud location. It dimples and punches the C-channels and studs for perfect fastener location and alignment. The building structure created by this roll forming system looks like it was made by a metalworking craftsman. Everything on this building system fits and finishes as you expect.
The frame of the Accu-Steel is roll-formed from heavy duty 18 gauge G-90 galvanized material that not only gives 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.
Accusteel Frame Buildings
- Steel does not warp, split, crack or creak;
