![]() Some are cast, many are heated and bent, and others welded to form the necessary unit. The brackets are usually made of powder-coated aluminum, stainless steel, or hot painted steel. ![]() Some are formed for siding profiles, while others attach to rafters, and a few to the roof deck. They are ‘J’, and ‘L’ shaped, even ‘F,’ ‘H,’ ‘V,’ ‘T,’ and ‘U’ shaped. Types of Retractable Awning Bracketsīrackets for awnings come in different shapes, sizes and metals. Different types of brackets are designed for different surfaces and locations. It is of critical importance to use the correct fastener type and size (length and diameter) depending on the substrate that the brackets are being attached to.ĭurable mounting brackets spread the weight or force along the wall while others put the strain in one area. ![]() Some brackets use lag screws for installation in to wooden framing others add anchors or shields to bite into stone or masonry walls. ![]() There is also the twist and lift situations caused by the wind they must survive. The bracket must withstand the downward stresses without buckling the wall, breaking, or being ripped out. Stud walls clad in vinyl, brick or wood handle bracket pressure, or compression, in ways different than those mounted in stone, block, concrete, concrete block (CMU) or steel. Multi-story buildings will withstand the strain of awning brackets differently than single-story walls. It is impossible to take every scenario into account though. Structural and Professional engineers use computer models to calculate all these forces for minimums and maximums and create designs for general or average situations. The mechanism used to extend and retract also exerts a force manual operation adds more stress than electric.īrackets and hardware must withstand vertical shear forces (gravity), horizontal (lateral forces) strain caused by wind, plus the increased downward pull on the frame when partially or fully extended. Of additional importance are what the brackets are made of, their shape, what material they will be attached to, and the hardware used to install them. The size affects the forces the brackets must withstand. The size of the awning and the type of bracket are very important considerations. The longer the awning, the more brackets needed to secure it to the structure. Retractable awning mounting brackets attach to the ends and depending on size to multiple points along the width of the awning frame. Now that we understand the forces at work let’s look at the brackets. If you’re looking at the large 53’x13’ model, that’s a whopping 689 square feet of canvas! The 14’x10’ has a generous 140 square feet, enough to make day-sailor fly. Wind force is another strain the supports must be able to withstand.Ĭonsider a 5’x3’ awning with 15 square feet of cloth, the same as most windsurfers. If the fabric gets wet, it increases the weight, which adds to the downward force. Retractable awning brackets have to deal with additional forces too. That is similar to the minimum strain and stresses an awning bracket experiences. Now extend your arm out straight to your side until it is horizontal. Think of holding a 5-pound weight in your hand at your side. However, when the canopy is extended or cantilevered, gravity multiplies that weight. The awning may be lightweight and not seem too difficult for the brackets to hold. This blog is recommended for home and commercial property owners seeking information on how to best secure and protect their awning investment.Īwnings come in many combinations of widths and projections and extend over windows, patios, decks and just about any outdoor living space. We’ll also take a look at some of the pros and cons for different awning brackets. The larger the dimensions, in both width and projection, the more brackets required to attach and support it. Retractable awnings rely on brackets to secure them to a building.
