SHELTER SIZE

The size of the Charleston shelter is expressed by the width and the depth of the roof area. For example, the roof of a 44’ x 25’ Charleston shelter is 44’ wide and 25’ deep, excluding the thickness of the 2” nominal size fascia boards. The number of columns, and the column placement is dependent on the size of the shelter, and height and slope of the roofing system.

The height of the front of the Charleston is dependent upon the size, specifically the depth of the shelter. For the models that are 25’ deep, the front height is 13’ 3’’, models that are 32’ deep, the front height is 15’, and models 39’ deep, the front height is 16’9”. The standard back height for all is 8’. Custom sizes are also available.

THE Charleston PACKAGE COMPONENTS
 

COLUMNS, EITHER LAMINATED WOOD or STEEL
Laminated wood columns are fabricated with Southern Yellow Pine, with dimensions engineered to sustain required load. The lumber is treated prior to gluing which affords full penetration of the core of each column.

If specified by EnWood’s engineers, steel columns will be designed to sustain required load.

EXTERIOR CURVED BEAMS
Pressure treated curved laminated wood beams that rest on the columns. Steel plates and bolts that connect the beams to the columns.

INTERIOR CURVED BEAMS
Laminated interior curved beams. Steel connections and bolts that connect the beams.
 

ROOF DECK
2x6 or 2x8 (nominal sizes) #1 grade, Southern Yellow Pine wood decking, tongue and groove and end-matched, is nailed to the top of the beams. Galvanized nails to attach the deck to the beams.

FASCIA
Pressure treated, two inch, #1 grade Southern Yellow Pine, fascia board to be attached at the eaves. Galvanized nails to attach the fascia to the beam ends and the deck.

FELT & SHINGLES
One layer of #30 roofing felt to be applied on top of the wood deck. 25 yr. 3-Tab fiberglass shingles, standard color Autumn Brown, other color options available upon request.

ROOF PITCH
The standard roof pitch for the Charleston is a 3/12 pitch.

DESIGN LOADS
The typical design load allows for:
12 pounds per square foot dead load
30 pounds per square foot live load
20 pounds per square foot wind load. (Equates to 100 MPH)

There are variables that affect the design sizes of the members, specifically the columns and the curved beams, and those variables generally include live load conditions which are usually location specific. Building Codes usually dictate the applicable loads to be applied in the member size designs.

PRESSURE PRESERVATIVE TREATMENT
As noted in the component list above, if wood columns are specified, the wood columns are fabricated with lumber pressure treated (prior to gluing) with Penta-WR type “C” (.6 pcf [6 tenths of a pound of preservative per cubic foot of wood] retention for “ground contact”). For applications where the treated member is not in ground contact, the treatment retention is .3 pcf. For the Charleston shelter, the exterior curved beams and the fascia boards are treated with pentachlorophenol, and the .3 pcf retention is used.

EnWood utilizes the pentachlorophenol treatment because of its premier qualities and the treatment does not discolor the wood and can be stained or painted.
