Arbor Lattice and Alumawood Patio Cover Manufacturing Information


You can be assured that the patio cover kit from Awnings Patio Covers .Com you are purchasing will enhance, protect, add value to your home along with more useful area.

The Alumawood Patio Cover is a watertight roof system with the same general look as the Arbor Lattice. The posts and beams are identical materials. The Lattice and solid Alumawood styles lend well to combine.

When purchasing a patio cover from anyone, there a few things you should pay special attention too. By doing so, then you can be assured that the patio cover you are purchasing will give you many years of reliable service for your needs. We encourage you to view our Gallery of Lattice Patios and our Gallery of Alumawood Patio Covers to see what true quality aluminum patio products look like. Both the Alumawood Lattice and watertight Alumawood Patio Covers are designed similar so you can install part of your patio cover with lattice and part solid cover. We also have mesh lattice screen tarps.   Our Carports are made of the same high quality material with a higher engineering standard.  We also have awning parts for your outdoor awning. The awning aluminum parts and awning supplies in cases are available to you depending on your awning style.

Awning Patio Covers will supply a set of engineered drawings and spans; please take note of the states listed with approved engineering stamp. If your state isn't listed contact your local Building Dept. to see if they will accept a state that is adjacent to you. Not all areas require a permit to install a patio cover.

Arbor Lattice Materials

The Lattice is available in 1-1/2"x1-1/2"x 1-1/2" or 2" x 2" x 2" both in a .018 thickness.

The ends of rafters, headers and Lattice come with a color matched end cap.

We quote our Arbor Lattice with all the components. All parts have the Wood Grain Embossed look. 3" Posts, 3" x 8" Beam, 2" x 6-1/2" Side Plates, 2" x 6-1/2" Rafters ( either in .024" or .032 depends on span and if a snow load is required ) and 1-1/2" Lattice Tubes.

The sheet metal screws used to attach the Lattice whether the 2 x 6-1/2" or 3" x 8" rafters are used have a Neoprene seal and washer to help keep water from getting inside the Arbor-Lattice tubes.
Optional: For extra seasonal shading add our Arbor Lattice Mesh Tarp system.

***  Steel C-Beams in 8" is used for our insert into the embossed 3" x 8" alumawood beam. The embossed aluminum material has a woodgrain look. By using the 3" x 8" steel insert you can achieve greater spans between post but you will need to have concrete footings to attach the posts.

Patio Cover Materials

The thickness of the awning "pans" depends on your particular application needs. The thickness for an awning pan is generally .018 gauge. This thickness works well with most awnings where there is little to no "snow-load" possibility or shorter spans. A thicker awning pan may be required or the use of beams must be used for heavier snow loads or longer spans.

Awnings Patio Covers offers four pan thickness in the Alumawood. The .018, .024, .032 are available in the embossed pattern; the .036 is only available in smooth finish.  The thicker awning pans at a slight additional charge. Several types and sizes of beams are also available for your special needs. 


***  Steel C-Beams in 8" is used for our insert into the 
 embossed 3" x 8" alumawood beam. The embossed aluminum material has a woodgrain look. We can use the 3" x 8" in white with our Standard Aluminum Patio Covers


***  Steel C-Beams in 10"

***  Aluminum I-Beams in 4", 7", & 10"

***  3" Steel Cloverleaf Beams
All of the beams have different weight and span ratings depending on the awning, patio cover or carport design you are seeking.

Post Style and Strength:

Awnings Patio Covers does not recommend what is called scroll posts: which are nothing more than two pieces of  " 1-1/2 " square aluminum tubing connected  together with an aluminum scroll.

We will only sell this type of post if specially requested by you the consumer and will meet engineering requirements.

Awnings Patio Covers uses a minimum of a 3" square .024 thick aluminum post.  For snow prone areas we use a 3" x .030 or 3" x .040 aluminum colonial post which depends on engineering. The Engineering of the larger projections, heavier live loads, and post spacing will require either a 3" x .040 aluminum colonial post or a 3" x .048 steel colonial post.If this is needed for your patio cover the alumawood standard embossed .024 post is slid over the heavier post to keep your alumawood style look. 

All freestanding patios and carports require a minimum of a 3" x .048 steel colonial post. Using these types posts we achieve a better engineered system. Freestanding awnings, patio covers, lattice or carports require the post be poured into a concrete footing for stability.

Delivered Patio Cover comes complete:

With an Awnings Patio Covers awning packages you will receive all the necessary components to assemble your awning.

Engineering:

There are some companies that are unaware of the engineering that is required to install an awning correctly. For those of you who are required to apply for a Building Permit (This will vary from town to
town) we have Engineering for 37 states (approved engineering for climates such as Florida, California, Colorado, Maine).

If your state is not among the 37 states you may not need a permit or your building department usually will accept the engineering from other states due to the similarities of weather conditions and proximity.

Please Note for your safety: There are some companies that are unaware of the engineering that is required to install an awning correctly. 
If your state is not among the 37 states you may not need a permit or your building department usually will accept the engineering from other states due to the similarities of weather conditions.

SNOW

Awnings Patio Covers engineered Patio Covers conform to National Building Codes in 37 States.  Below you will find a list that gives you specifications that the patio needs to slope for a given span and maximum spanable distance per Live Load to pass inspection for most parts of the United States. Your local Building Department can and will inform you as to the Snow and Wind rating codes for your area. You want to tell them it is an Open Aluminum Lattice Cover.  These will be the same as for your local company. They should have this information close at hand. Remember this information is for your benefit. A local non-direct third party is your best attempt as to what is required in your area, i.e.; if possible your local building dept.---you and your families safety is a concern of ours also.  Span in general is the unsupported distance between the structure.

The Arbor Lattice does not have to be sloped to drain. For extra seasonal shading add our Arbor Lattice Mesh Tarp system. Our Mesh Tarps are not designed for high winds or snow.

With our standard aluminum raingutter - header or an intermediate positioned "C" or "I" beam.) Slope, that is required minimum in inches of drop ( .40" per foot of projection [allow ½" per foot of projection as a safe margin ) An intermediate positioned "C" or "I" beam with posts can be placed at mid-span of projection. By doing this you will reduce the span between supports and this will allow for thinner pans to establish your projection. This sometimes will require you to install concrete footings for the patio cover posts.
Our Patio and Carports can be designed for Snow Loads of up to 60 lbs. per square foot and Wind Factor of up to 90mph.  Snow weights approximately 5.25 to 5.5 pounds per cubic foot of snow ( 12" x 12" x 12" ) which is +/- = 1" in depth of water on a 12" x 12" area. Some areas may have a slightly higher water content than 1".  The Patios and Carports Designed slopes below are based on the 2 1/2" Super 6 Pan ( Alumwood Patio Covers).
Minimum Inches of Slope required for a projection ( the distance you want your awning to extend from your home ) = 3 -1/4 ", 9' = 3 - 5/8", 10' = 4" , 11' = 4 - 7/16 " , 12' = 4 - 7/8" , 13' = 5 -1/4", 14' = 5- 5/8 " , 15' = 6" , 16' = 6- 7/16 ". Remember your concrete patio slopes also. 
Examples are for a 10 pound per square foot and 90 mph wind factor design:
Patio pan thickness for the following projections .018 will span up to 13 '- 3", .024 up to 16' - 3", .032 up to 18'- 8" and .036 up to 19' - 4". The .036 pans are available in smooth only. 

Note: 
Exposure "B" has terrain which has buildings, forest or surface irregularities covering at least 20 percent of the ground level area extending one mile or more from the site.  
Exposure "C"
has terrain which is flat and generally open.  Extending one-half mile or more from the site, in any full quadrant.

States that have approved Engineering:
Alabama, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Georgia, Idaho, Indiana, Kansas, Kentucky, Louisiana, Michigan, Mississippi, Missouri, Montana, Nebraska, Nevada, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oregon, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, Washington, West Virginia, Wyoming.

WIND

We can engineer up to 90 MPH Wind Factor. This may seem quite an extreme for wind but this is designed to protect against the Blustery umbrella effect of the wind.
