Aluminum is one of the most used metals in today’s society – bullnose aluminum extrusion in Johannesburg it can be found across a number of industries, such as construction and commercial, and in a number of applications, such as beverage cans and appliances. When choosing a manufacturer of aluminium extrusion for supplying the metal that you use in your workplace, however, it is important that you carefully consider which one will be best for your needs.
The manufacturer will begin by removing the aluminium from deep within the earth’s crust (either as bauxite ore or feldspar). Often, the Bayer’s method, Wohler’s method or Hall Heroult method is chosen to remove the metal in its molten form. It is then hardened and moulded into whatever shape the manufacturer desires. When the aluminium is extracted from the earth in its solid form, aluminum extrusion profiles it will be passed through a number of mechanical processes that are designed to give the metal its desired shape. These processes include: rolling, drawing, forging, spinning, piercing and extrusion.
Regardless of whether aluminium has been found in its molten or solid form, the manufacturer will then pass it through either a hot working or cold working process to prepare it for their customers. When using the hot working process (the most popular of the two), a billet will be heated to a temperature of over 79 degrees Celsius, which will allow the aluminium to be easily distorted and placed into its desired shape.
The reason for the popularity of the hot working process over the cold working one can be fully realized when you compare aluminium extrusion to squeezing toothpaste out of its tube. It is much easier to extrude the metal when it is malleable, meaning that it must have been heated to a certain temperature.
Finally, the aluminium will pass through an extrusion and drawing process that runs almost parallel to each other. This is the final step in the whole extrusion process and is the step that gives the metal its entire shape. Deep drawing, for example, is used give the metal a cup, conical tapered, cylinder and seamless tube shape. For less curved shapes, profile aluminum extrusion the drawing process is skipped.
Once you are satisfied with the processes and methods utilized by a potential manufacturer of aluminium extrusions, you can begin submitting your orders with them. If, after your first delivery, you are still satisfied with the manufacturer based on the promptness of the order being filled and the quality of the aluminium that you receive, you can continue the relationship.

Aluminum is the preferred material for door and window frames due to its inherent structural and aesthetic properties. Doors and windows made of aluminum frames with glass glazing may look the same from a distance but take a closer look and the difference between quality product and one that is fabricated by a local fabricator becomes apparent. If you are investing in doors and windows it pays to buy only quality products.
Seamless integration of hardware with aluminum frame
The looks as well as performance of aluminum windows are dependent on and influenced by the way hardware is integrated into the frame. If the window has hinges then the way hinges are designed and fitted to the frame has a bearing on ease of opening and closing as well as reducing gaps and thereby preventing energy losses. Quality manufacturers design and manufacture their own hardware to go along with windows and doors.
Most general fabricators do not work to tight tolerances while fabricating frames from aluminum profiles. There can be gaps between joins and this can look unseemly and if the frame sections are not well aligned, closing and opening them becomes a chore. Quality manufacturers also include thermal breaks and a foam core that provide additional insulation.
Quality manufacturers offer aluminum in a variety of finishes such as natural anodized finish in various shades, metallic colours, permanent colour fast powder coating and woodgrain foil overlay for a natural look. You can go a step further and choose aluminum frames that have one colour finish for interiors and another on the exterior to match building facades.
Single or double or triple glazing?
When double glazed windows offer so many advantages there is little point in saving some money by choosing single glazing. Double or even triple glazing is better from energy conservation as well as acoustic insulation perspective. Some advanced manufacturers offer gas filled and totally sealed double glazing. You also have the choice of blinds integrated inside the glazing, which makes for a neater appearance and ease of use. When one talks about glazing, it must be kept in mind that glass varies widely. It is recommended to look for windows with low E internal glass and possibly toughened glass so that, in the event the glass breaks, the floor is not littered with glass shards. You can also select glass that is coated to reflect heat and thus reduce energy consumption.
How secure are the aluminum windows?
Quality manufacturers offer windows that conform to British Standards PAS 24:2012. Material, design and manufacture of the windows makes it difficult for would be burglars to force the windows. You should look for multipoint steel locking system and internal glazing for better security.
It pays to invest in world recognized brands offering quality aluminum windows. Windows look perfect from inside and from the outside. They will be easy to operate and you will enjoy their use for years with minimum maintenance. It may cost more initially but a quality aluminum window also adds to the value of your house.
Why And Why Not Opt For An Aluminum Sliding Door
Aluminum Sliding doors are stackable doors of many panels that move entirely to one side stacked neatly together. Their earliest form can be seen in traditional Japanese architecture. Now they are a definite feature of most public spaces like malls, hospitals etc. They are manufactured with a sophisticated track and frame system with a superior sliding mechanism. They offer an energetic look to any property and helps to maximize the light in the room and achieving the full potential of the view. They are a feasible alternative to bi-folding doors, with a sash width going up to 120 cms.
What are the advantages of automatic aluminum sliding frame doors
· Disabled friendly - These automatic doors open and close on their own.
· Safety features - they have up to date safety features and wireless remote control as well. Timers allow security personnel to lock the doors without having to be present near them.
· Gives Footfall account - the number of times the door opens can be obtained. This is useful footfall information in malls or shops.
· Style and variety. These doors are available in aluminum, which can be painted to depict the company's logo etc. in an office. The latest frameless glass doors are very popular among offices, where they allow an uninterrupted view of the proceedings outside.
· They allow for heat or coolness retention since they open only when somebody approaches the door
What are the parts of an automatic aluminum sliding door
An automatic sliding door normally consists of the following parts
· Carrier wheels
· Sliding door panel(s)
· Sidelite panel(s)
· Lock and activation/ safety setup
The door panels are made from extruded aluminum profiles and safety glass for visibility.
Applications of automatic sliding aluminum doors
· Higher the traffic through the doors, heavier will be the moving panel.
Good for offices, hospitals, malls, banks, restaurants, art galleries etc.
· Fire and smoke door applications
· Energy conservation
· Security control, directional control or card access control applications
Testing procedures - The doors are made to open and close automatically for forty eight hours at a stretch.
How are they assembled?
· When they are shipped, the instructions for installation accompany them.
· The instructions are to be read fully
· Two or more people are required to install it
· Be careful when handling the glass
· Operate power tools carefully according to manufacturer's instructions
What is weatherstripping?
Weatherstripping is sealing the sliding panels from the elements of the weather by an insulation strip. This has to be replaced when it gets worn out.
What are the things to watch out for in automatic sliding doors
· Installation is not easy - the tracks have to be perfectly aligned, and more than one person is required to install a sliding door.
· The track attracts dirt because it is a series of grooves in which dirt accumulates very fast
· The doors get jammed sometimes because of the rust and dirt of the metal parts. They have to be changed in this case. Regular oiling helps too.
· If there is a power cut, they will get jammed and they have to be forced open.
