Metal Fabrication


If your business relies a lot on sheet metal, finding the right manufacturer or supplier is key. Here’s how to pull that:

Competence

Getting the thickness right is crucial when it comes to sheet metal work, says Makezine. A company that has a reputation for being competent at delivering these solutions is a good addition to your list of prospects.

Experience

Nothing beats experience. If you want results that offer both quality and reliability, then you’ll want a supplier that has had extensive experience in the business. If the company has been around, offering its services to clients for more than a few years, then that’s a good sign.

Capacity

Be sure to ask the manufacturer if they’re well able to handle the volume of your orders. Some might not be equipped to handle high volume deliverables while others might not accept small volume batches. Knowing which range you fall into makes it easy to pick the right manufacturer for sheet metal work.

Equipment

You can easily swing by the work site of the company for a look at the facility and to check if they have all the necessary equipment. If the equipment you see are old, slow and seems to break down often, the company might not have the equipment to provide you with excellent results.

Reviews

Online feedback offer you a glimpse of what other customers think about the experience of working with the company and the likely results you’ll get.

Customer service

Problems are going to happen. That’s a given. But what isn’t is the service level and quality of assistance you can expect from your supplier or manufacturer. By getting one with high service levels, you’ll find it much, much easier to work with them, fix possible problems and achieve your goals in the future.

Are you on the hunt for metal fabricators? If so, you should not rush into finding someone who can aid you in creating equipment, parts and various structures, whether they are made from aluminium, cast iron or stainless steel. A fabrication firm will specialise in many different things, including detailing, design building, drawing and reading blue prints, etc. From making basic equipment platforms to putting together a set of stairs or a catwalk, the jobs that a fabricator is faced with will vary. The fact that metal tends to form the framework of most public and private facilities means that you need to be on the lookout for a fabrication company that possesses the following skills.

Dedication to Quality

Metal fabricators will be committed to providing their customers with quality products at all times, not to mention excellent customer service. Whether they are in the process of sand blasting, cutting, punching holes in metal, flattening stainless steel or reshaping metal to match the blue print, they must be focused at all times.

Project Experience

The breadth of experience that metal fabricators possess ought to be extensive. How long have they worked in the industry? Do they have a long list of clients? Are their techniques, technology and fleet of equipment suitable for the task at hand? Keeping on track with logistical management will reduce downtime, so take this into account too.

Manpower Performance

Although metal fabricators will be able to work alone and on their own initiative, operating as part of a group will ensure the job is done quickly and to a high standard. There should always be a fabricator on stand-by, so that the professional can step in if need be. Ask about the expertise level of the workers you hire to make an informed decision and keep in mind that the larger the workforce, the better.

If you’re like most people, you prefer stainless steel to almost any other metal, especially if you need something resistant to corrosion and easy to fabricate. However, most people don’t realise why stainless steel is so popular or its many advantages over other metals.

Resistance To Corrosion

All stainless steel metals have a resistance to corrosion, though low-alloyed grades will only resist corrosion in traditional atmospheric conditions while highly alloyed grades can be resistant to alkaline solutions, acids, and chloride environments, even at high pressure and temperature.

Resistance To Temperatures

Some grades can resist scaling and remain incredibly strong at higher temperatures while others are exceptionally tough at cryogenic-level temperatures.

Easy To Fabricate

Almost all stainless steel options can be manufactured quickly and efficiently, which can include machining fabrication, forming, welding and cutting. Therefore, it is an excellent choice if you want to cut or shape it to your particular needs.

Strong

Because it is strong and thin, it can be used in various designs that need something sturdy without added bulk or weight. Therefore, it can help reduce costs to manufacture the item and reduce its weight for shipping and daily use. Whether they use cold work hardening or heat-treatments to become stronger, stainless steel can be as strong as or stronger than many metals.

Hygienic

Because it can be cleaned easily and doesn’t stain, it is more sanitary than other materials. Many kitchens, hospitals, pharmaceutical companies and food industries use it for almost every surface imaginable to keep bacteria out of food and medication.

Aesthetic

While most people wouldn’t associate it as being aesthetically-pleasing to the eye, it does come in various finishes. Therefore, it may not look like stainless steel and will still be of exceptionally high quality. Plus, it is easy to care for and looks great anywhere.

As a process, bending a tube requires the tube be loaded into a tube or pipe bender and secured in place between two dies. Mechanical force is then applied to push the stock against a die forcing it to conform to that shape. This was press bending which was probably the first bending process used on cold tubing and pipes.

Rotary Draw

These are the most popular machines for bending tube or solid pipes for uses such as frames, handrails, handles. The Rotary Draw method creates attractive bends.

Roll Bending

Tube bending can be done by passing the tube through rollers which apply pressure. Coils of pipe can be produced using this method and long bends.

Heat Bending

A heating coil is wound around a pipe which is heated to as 2,000 degrees Fahrenheit. Pressure is applied to the hot pipe to bend it. The pipe is then cooled with water or air.

Devices Used for Bending

Mandrels are inserted into tubes to add extra support while bending. These might be steel rods or metal balls linked together. Springs can also be inserted into the copper pipe. The spring will have a slightly smaller diameter than the pipe.

Power for Bending

Tube bending machines can be human, hydraulic, pneumatic, or electric powered. Bending tubes in fabrication are done by various methods. In a recent article in the Journal for Cleaner Production, the author notes that a significant energy savings can be achieved by using electricity to power tube bending machines. The efficiency of the process was also found to be increased by up to 50% by using electricity.

This tour around the bend and back again gives a general overview of the processes involved in bending metal tubes using press bending, rotary, roll, or heating methods and the device and power used in bending.

Unless you work on roofs frequently, you may have never heard of roof flashings and may not know what they’re used for and why they’re necessary. Flashing is needed to direct the water flow around any openings in the home, such as vents, skylights, and windows. Without them, water can seep into the walls and roof, causing damage, creating mould and other problems. If you’re currently building a new home or want to remodel the outside of one, you should consider your options carefully to ensure that you remain safe from water damage.

Materials

Flashing can be made from various materials, including composite, plastic and sheet metal. While sheet metal is more durable, it is also more expensive. Stainless steel and copper can also be used. While plastic options are available and are less expensive, they can wear quickly if the parts are exposed to sunlight.

Dormer Options

For dormer windows, metal is usually the flashing of choice. The squares are placed between each row of the material or used as a strip to run under the material and around the dormer.

Skylights

If you’re thinking of adding a skylight to your home, roof flashings are a necessity. Skylights can give you more natural lighting, but they can be detrimental if not placed properly or flashed correctly. Generally, the flashing is a continuous piece around the skylight, and the window itself will be raised to allow enough room for the roof flashings.

Vents

Ventilation is a necessity for various parts of the home, including kitchens and bathrooms. If you’ve got currently installed vents, the flashing may need to be altered. If you’re adding new vents, extra work may be required to ensure that there is enough space for the vent and the flashing material.

Metalworking involves forming metal, cutting, and joining. In the metal work business, the engineer’s plans are marked to the pieces for machining or manufacturing.

The Process in general

Metal forming could also be called deforming. Mechanical forces modify the metal. In rolling the metal is passed through a pair of rollers. If extrusion is used, the material is pushed under great stress through an orifice. Metal can also be stamped by a press. Metal can be formed by bending and shearing. In all of these cases, heavy equipment is involved. Cutting is the removal of excess material by chipping, burning and other processes such as turning, milling, drilling, grinding and sawing. Welders can be used, water-jet, and lasers. Joining can be done by welding, brazing, soldering, or riveting.

Choose Experience

Look for experience in both longevity and the work you need accomplished. If they have been in business for many years, they should have references. Also, what is the area of expertise? Some fabricators specialize.

Choose Location

Where is the company located? Can they serve your metal work needs in your area? They need not be a local company. Depending on your needs, the work can be done remotely, or a crew sent to your site. Your needs determine the location.

Choose Quality

What certifications does the company hold? What are the training requirements of employees? What reviews are available for their work from independent sources? Can you look at other similar work they have done? Take your time to ensure you employ the business that will give you a quality service or product. According to Katherine Hawkins in her article “Tips for Choosing a Product Manufacturer”, do your homework. Before making a commitment, take the time and effort to tour the facility. Get to know the business, its abilities, and its people. Choosing wisely take effort.
