In some instances your local area may require an engineered set of plans in order to approve the installation of your awning. Every Rontimco awning has been fully engineered to the highest standards of materials quality and structural integrity. A set of the actual engineering reports is available should you need them. The engineering for our patio cover and awning kits is based off of Amerimax Engineering. If a permit is being pulled it is a good idea to have the engineering and plans approved before you purchase. Rontimco is not responsible for permit or associated information. Awnings may be attached to a building or be freestanding. Prices will vary depending on this and other factors. SUPPORT BEAM AND HEADER TYPES
Cloverleaf - The Cloverleaf beam is the same material used as posts for poured footings. The Cloverleaf beam is 3 inches by 3inches and constructed of 0.041 inch thick steel. POST TYPE AND GROUND ATTACHMENT | Concrete Slab Attachments | Awnings that will be attached to a concrete slab will come with Aluminum posts that are 3 inches by 3 inches and are 0.040 inches thick. All hardware and brackets are included for this type of mounting. Remember to keep several inches away from the edge of your slab to avoid cracking your concrete. | | Wood Deck Attachments | Awnings that will be attached to a wood deck will come with Aluminum posts that are 3 inches by 3 inches and are 0.040 inches thick. The brackets for a wood deck attachment will be included but the Lag screws or bolts will not be included. Please see Wood Deck Attachment Engineering for appropriate lag screw and bolt descriptions. | | Footing Attachments | Footings must be poured with the post being embedded into the concrete. For this reason you will your quote will indicate a post size that is 2 feet longer than the awning height. This extra 2 feet is intended to be used in the footing. The post is 3 inches by 3 inches and constructed of 0.041 inch thick steel. No brackets or bolts are needed for a footing attachment. Customers must provide the concrete and steel bar for reinforcement for each footing. Each quote with a footing attachment will indicate a footer size. This amount should be cubed for each footing. Please see Footing Engineering for footing details on post depth and steel bar reinforcement. |
*All freestanding structures require a pourd footing. HOUSE ATTACHMENT TYPE | Wall Attachment | If an awning is to be attached directly to the wall, the wall should have a stud spacing of 16in on center. If this is chosen, 4 inch lag screws will be sent with the kit to attach the C hanger to the wall. Engineering requires at least 2-1/2in embedment into the stud. | | Ledger Board | If the studs are spaced greater than 16in on center, customers should utilize a ledger board. Engineering requires 2 inch thick ledger boards. For most places a 2x6 or a 2x8 is acceptable. Use # 2 Douglas fir or better. Customers are responsible for the ledger board and its attachment to the house. The C hanger will attach to the ledger board with 2 inch screws that will be included in the kit. | | Eave Attachment | Eave attachments require a 2 inch wide fascia. The fascia should be reinforced using Simpson bracket A34 on the back of the fascia to the side of the rafter. Eaves are allowed a certain amount of over hang per snow load and projection. See Eave Engineering for details. |
GENERAL ENGINEERING | Slope | The minimum slope of the roof panels along the projection is 1/2 inch per foot. | | Wind Load | The wind load for most kits is 90 MPH. We can accomodate up to 110mph. Most kits will be engineered for an exposure B area. This refers to urban or suburban areas, wooded areas, or other terrain with numerous closely spaced obstruction having the size of single-family dwellings or larger. Exposure C is also available. | | Snow Load | Snow loads are given in pounds per square foot and range from 10 to 60 PSF. This measurement is also referred to as live load. In most cases even light snow areas will begin at a 20lb load. A 10lb load is for areas that receive no snow. Please contact your local building department to verify the snow load for your area. | | Post Spacing | The post spacing is indicated for each kit. If you don't like the post spacing, please call Rontimco and we can adjust it. Adjusting it in the field may void the engineering rating. The side overhang (from post to end of header) cannot exceed 25% of the actual post spacing. | | Length | Lengths are given in 1 foot increments. The distance from side to side. Fascia covers are not included in this measurement. The length cannot be less than 75% of the projection. So for a 10 foot projection you couldn't have less than a 7.5 foot length. There is no limit to how long these kits can be. | | Height | This is the distance from the ground to the bottom of the header. In other words this is the post height. | | Projection | The distance from the house to the gutter/fascia. Or in the case of a freestanding it is the distance from the gutter/fascia to the gutter/fascia. | | Clear Span | The distance from the house to the posts. Or in the case of a freestanding it is the distance from one row of posts to the next row of posts. | | Overhang | When a cantilever is added the over hang is the measurement from the center of the post to the end of the gutter/fascia. | | Permits | If a permit is being pulled, customers are responsible for getting these plans and the engineering approved by the local building department or appropriate organizations. For accurate requirements for snow and wind loads, please contact your local building departing or authority. |
