Cutting is the separation of a physical object, into two or more portions, through the application of a directed force. For metals, there are many cutting methods which can be grouped by the physical phenomenon used. Below is a list of some of the cutting techniques utilised at AAP Fabrications:
- p forming: sawing, drilling
- Shearing: punchiChing, stamping
- Abrading: grinding
- Heat: flame cutting, plasma cutting, laser cutting
- Electrical discharge machining (EDM)
Bending is a manufacturing process that we use to produce angles most commonly in sheet metal. Typical products that we make using this process are rack protectors, concrete moulds & boxes such as electrical enclosures and rectangular ductwork.
Notching is a process which cuts stock without the formation of chips or the use of burning or melting. In general, if the cutting blades are straight the process is called shearing. The most commonly sheared materials are in the form of sheet metal or plates.
Drilling is a cutting process that uses a drill bit to cut or enlarge a hole of circular cross-section in solid materials. The drill bit is a rotary cutting tool, often multipoint. The bit is pressed against the workpiece and rotated at rates from hundreds to thousands of revolutions per minute. This forces the cutting edge against the workpiece, cutting off chips (swarf) from the hole as it is drilled.
Welding is a fabrication process that joins materials, in our case metals, by causing coalescence (to join into a single mass or whole). This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. At AAP, we use different methods to weld mild steel, stainless steel and aluminium. The welding techniques we use primarily are: MMA / MIG / TIG
Galvanising is the process of applying a protective zinc coating to steel or iron, to prevent rusting. Typical applications where galvanising has been used at AAP are external structural components. The protection provided by galvanising is insufficient for products that will be constantly exposed to corrosive materials such as saltwater. For these applications, we suggest a stainless steel solution.
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Powder coating at AAP is mainly used for our products that are going to be visible to the end-user and require a durable corrosion-resistant finish.
When it comes to steel fabrications, you need highly trained and experienced steel fabricators to make sure all work has been undertaken at the highest quality and standard. All our steel fabricators are fully qualified for the job at hand. We are fully insured and comply with health and safety regulations.
We have an in-house detailing service so that you can see exactly how your structure or steel fabrications will be built. Whether you require a steel frame or a stainless steel balustrade , our Jarrow office can help.
We cater for the needs of a wide range of clients with a range of services available including steel fabrications, welding and the erection of steel structures.
