In the vast and diverse world of angle brackets for gutters, several types perform optimally under specific circumstances. Choosing reinforces the need to understand these differences when selecting the appropriate angle bracket for a particular guttering system.
This designation is meant to reinforce the external aspect of gutters where downspouts are connected to the horizontal top roof overhang. Unlike similar intermediate and internal supports that have a role in external angle brackets, external brackets are intended to be mounted on the fascia board and provide support under the gutter. They also provide a level of water channeling into the gutter, especially during heavy downpours, without overflowing.
As the name implies, these brackets are installed inside the gutter, providing extra reinforcement and support to its shape and structure, ensuring that collected rainwater has an uninterrupted channel to travel harmlessly to the drainage system. Internal brackets are necessary for wider gutter profiles susceptible to sagging or bowing under severe weather elements.
A floating angle gutter bracket mounted on the wall or fascia without directly supporting the gutter has its advantages in design and application flexibility. It is not embedded into the support structure of the building but 'floats' around it. They are ideal for helping to offset the width of the gutter, provide additional support needed for larger gutters, and distribute the load evenly across a broader area to reduce sagging. Also, since floating brackets do not penetrate the actual roof overhang, they reduce installation problems with the bracket and blocking, which may otherwise have been an obstruction to the installation or leakage points for the roof, resulting in water damage to the house.
Unlike standard angle brackets, which function to support the open ended angle formed between two facets in a gutter installation, return angle brackets also serve a more aesthetic construction function. In addition to providing the necessary support to ensure the gutter system is level and water has a path to drain, return brackets are designed with a return lip that is turned up against the structure of the building. This aims to prevent water splashing back to the walls and creating a problem in the first place.
Picking the right gutter angle brackets depends on several factors, one of which is material consideration. In most bracket designs, however, the concept is that they should have some resistance to corrosion, a good level of strength and be compatible with the gutter material so as not to cause any electro-galvanic action.
Because of its excellent corrosion-resistant properties, stainless steel is arguably one of the most common materials used for angle brackets in coastal or high-humidity regions. Stainless steel is run as a highly durable, low-maintenance material with the strength that makes it suitable for heavy-duty supports even under the most adverse weather conditions. Stainless steel brackets do not require frequent curtailment or replacement of the elements, making them a cost-effective long-term solution.
This material is lighter but has comparable strength to stainless steel. Because they need to be powder coated, painted, or for some other reason, aluminium gutter angle brackets come in various colours, thus offering design flexibility to blend with the house fascia or roof. For instance, they can be practical and, at the same time, aesthetically appealing to the homeowner. One of the properties of aluminium, though, is that they have to be treated and possibly installed with non-conductive materials to prevent electro-galvanism from occurring.
Plastic brackets are a popular choice with homeowners who have installed vinyl or plastic gutter systems. Because of their lightweight design, they are easier and quicker to install, and due to their nature, they are resistant to corrosion. However, plastic brackets cannot carry a load like metal brackets and are more suitable for moderate weather conditions. Since the application calls for lighter materials, plastic or PVC brackets are more commonly used in residential structures rather than in commercial or industrial applications.
Bracket plates are made from galvanised steel, which is a milder and cheaper metal, as with most premium metal angle brackets. Because of its coatings with zinc, it aims to protect the steel from moisture and thus rust. Also, while not as long-lasting or as strong as stainless steel, galvanised steel brackets provide a sturdy, weather-proof, and inexpensive solution where brackets have to be used - such as in working-class or industrial environments.
Gutter angle brackets have commercial applications and support essential structures in residential houses, as discussed earlier. They are also widely used to install and maintain effective rainwater drainage systems in commercial and industrial buildings, large scale warehousing and storage facilities with complex roof structures, and in extreme weather conditions.
Large factories often have extensive roof areas, resulting in considerable water runoff that must be effectively managed. Angle brackets ensure the heavy-duty guttering systems are supported, aligned and have the strength necessary to withstand the load created by the tremendous rainwater flow across both the roof and the gutters.
Bracket support is also needed in places like hospitals, schools or shopping centres, not to mention tall and complex architectural structures like skyscrapers where they are used to ensure the bracketed gutter system functions as it should.
Warehouses are another such commercial installations where angle brackets help support massive gutter systems over large roof spaces. Angle brackets are much needed to prevent sagging or overshadowing, which would compromise the very integrity of the installed gutter systems.
Angle brackets are widely used in agricultural settings with large barn-style buildings and greenhouses with extensive roof areas and heavy rain or snow loads. Angle brackets are critical to keeping the gutter systems lined up and supported, thus protecting valuable crops and livestock from water damage.
Angle brackets with heavy-duty load support are necessary for manufacturing facilities with large industrial hoist and assembly line garages with flat roofs. Angle brackets in these places keep the gutter systems aligned, thus ensuring no water collects on the roof, which would otherwise pose safety and structural concerns. In facilities exposed to chemical spills, dust or other contaminants, galvanised steel or stainless steel brackets may be required to prevent corrosion and rust.
Because of the critical role the gutter angle brackets play in keeping both the structures and the contents protected from water, it is important to select the correct type of bracket for both the gutter and the structure, taking into consideration the length of the roof, load it would carry and the weather elements.
It is important to select the right angle brackets for the gutter system since they protect the structure of the building and ensure water is channeled properly. Any given bracket should be made of a material that is compatible and has to possess certain attributes.
At least standard size angle brackets for gutters are available for common types of gutter systems. However, custom brackets may sometimes be necessary for unique or non-standard gutter profiles. This is especially true for older buildings or custom architecture where a specific design needs to be accommodated.
Regular inspections of the angle brackets should be done at least twice a year, preferably in the spring and fall. More frequent checks may be necessary in regions with extreme weather conditions or where the brackets are exposed to heavy loads, such as after a snow, rain or storm.
Gutter angle brackets can be easily replaced without having to remove the entire gutter system. In fact, this is one of the attractive features about angle brackets; they can be easily replaced without dismantling the entire gutter system, especially when the brackets are designed for easy removal without the need to touch the guttering.
In general, the metal angle brackets for gutters do not require any maintenance. Unlike metal brackets that require some form of treatment, such as painting or re-coating, plastic brackets require no maintenance at all.
By providing support and alignment to the gutter system, the angle brackets help distribute the load evenly. This reduces sagging, bending, or other forms of wear and tear, which ultimately prolongs the life of the gutter.
