This involves the location, style and strength of connections from the awning or canopy to the building or to its foundations.
Awning attaches to house/structure either at the wall, eaves/fascia or roof top.
An awning is an architectural projection that provides weather protection, identity or decoration and is wholly supported by the building to which it is attached. An awning is comprised of a lightweight, rigid skeleton structure over which a rigid covering is attached.
(see Illuminated Awning)

Fabrics that are coated are usually done so with a liquid or semi liquid product. Coatings can be urethanes, acrylics, PVC, neoprenes, and many other types of substances. Knife over roll: the material rolls past a knife that acts to spread a liquid substance across the width of the fabric. Extrusion: dry chemical mixes are heated and mixed through an extruder and then passed through a roller or die to flatten and spread the substance across the width of the fabric.
Fabrics coated, covered, or treated with various substances to make them stronger and/or more resistant to weathering elements. Coating substances include rubber, resins, plastics, PVC, melamine?s, oil finishes, etc.

Di-Electric Welding (Also referred to as "RF welding".)
Certain fabrics with "thermoplastic" properties, such as vinyl, can be welded together with various machines that use high frequency electrical impulse. A high frequency electric impulse is sent through the fabrics by means of a bar or table and this mixes up the molecular structure of the thermoplastic materials. When the bar or table is removed, the two fabrics are melted or welded together. This differs from Hot Air Welding, but the end result is the same.
Fabrics can stretch and shrink in the warp, fill or bias directions, depending on the construction and/ or fibers employed. When a fabric is dimensionally stable, means that stretching and shrinking have been controlled to a certain degree.

Components that make up the structure of an awning.
A metal structure of an awning used to give shape and design. Typically frames are made from aluminum or steel and are joined together by welding or by specially engineered fittings. Graphics G & J Awning is capable of providing various types of graphics. One or several techniques may be applied to any given project. o Adhesive Applying a pressure sensitive vinyl to the surface of an awning. o Cut-out Lettering Lettering or graphic elements that are cut out of a fabric and replaced from behind with letters or graphics of another material. o Eradication The process of removing the colored topcoat from a material allowing the white base to show through. This process can only be done on materials designed for eradicating. o Painted / Hand Painted Hand painted directly on the surface of an awning. o Pressure-Sensitive Graphics Pressure-sensitive vinyl film is cut by hand or by computer to a desired design and then adhered in the proper register on the fabric as decoration. o Welded (heat-sealed) The process of using a radio frequency welder to permanently bond the graphic to the primary material.
Freestanding Awnings use no other structure to help support the awning and relies solely on the posts. For this reason the posts must be poured into a concrete footings, footing size will be determined by the engineering.
Attaches to the end of the awning pans, water runs in and is diverted to the downspout.
