The PVD process is also more environmentally friendly than alternatives such as electroplating and painting. Unlike these there are no gases, water waste and other residue released. Also important to note is that the colouring process does not limit the recycling value of the stainless steel.

The friction that occurs between the tip of the drill bit and the angle iron surface creates heat. This accelerates the rate at which the drill bit dulls. The more the drill bit dulls, the more it generates heat. Therefore, you should drill cautiously while controlling heat buildup to keep the drill bit sharper for long.

The PVD process can also be used on stainless steel jewellery – achieving some striking colours. The PVD stable colours are gold, rose gold, coffee, black, dark grey, and blue. All these colours are available in a polished, satin or matt finish according to the product surface polish finish.

The first step is sanding and painting the angle iron. Use an orbital sander or 80-grit paper to sand down the surface of the angle iron. This should be done meticulously. Therefore, go over the surface of the metal sheet at least twice, both front and back. You should then paint the angle iron pieces using a primer followed by your preferred paint color once the primer dries. Silver is the most preferred color for angle iron.

Tap the sides of the drilled angle iron using a hammer to prevent sharpness or protrusion commonly caused by metal shards left after drilling. You should then apply a machine coolant to clean the new angles. This leaves an ultra-smooth surface that can be used for any purpose.

The coloured surface coatings that can be obtained using PVD include: gold (TiN), rose gold (ZrN), bronze (TiAlN), blue (TiAlN), black (TiAlCN), as well as a dark red (ZrN). This ceramic coating which is produced is very thin, making the texture of the underlying finish still visible. These PVD colours will not fade over time and have the benefit of being more uniform in appearance and more abrasion-resistant than colouring which is done by the electrochemical processes.

PVD coloured stainless steel, used in the creation of sculpture, jewellery and phones, is also sufficiently robust to be specified by interior designers and architects for interior and exterior architectural use. We take a snapshot of this very versatile medium.

When it comes to stainless steel you’re not just restricted to simply silver. There are a rainbow of colour opportunities which can be achieved through the Physical Vapour Deposition (PVD) process.

Though it seems simple, drilling through angle iron comes with some challenges. Whether you are a beginner or an expert DIY, acquainting yourself with the basics of angle iron drilling can help. You should also choose the right drill bit and wear protective gear. Visit our website if you’d like to learn more about angle iron. We hope this article has given you an understanding of how to drill through angle iron. Feel free to contact us if you have any questions. Thank you so much for reading!

Jeff Fisher Jr. started as KF Machinery in 2008, and rebranded the company as MetalReady Machinery in 2018. The goal was to offer Metal Fabricators the best machinery in the market, leveraging Jeff’s vast experience in equipment sales and fabrication. MetalReady has surpassed that goal over the last five years by delivering the highest quality of service to their customers. MetalReady has consolidated several popular product lines under one umbrella, emphasizing values such as integrity, being informative, and being innovative with their customers.

During the process, first of all the stainless steel is cleaned to make sure that the coating will bond well. The steel is then placed in a vacuum chamber with a “target” metal; this will be used to create the coating. A high vacuum level is needed in the coating chamber, then a small amount of argon gas is introduced. A high voltage circuit is used in order for the stainless steel and target to bond or adhere. This allows the argon ions to bombard the target to release atoms of the target metal, which are deposited on the stainless steel substrate as the coating. This PVD process is called sputtering; resulting in the deposition of plasma on the stainless steel surface which gives it its new strength and shine.

With the surface ready, you can drill holes in the angle iron. A carbide-tipped masonry drill bit is the best option for drilling angle iron. Ensure that the drill bit has an 80-degree sharpened tip. Using this drill bit gives you maximum control while minimizing pressure on the angle iron. This reduces incidences of cracks or other damages. Ensure that you stand directly above the metal surface as you start drilling. This makes it easy to keep any reactions from the drill in check.

PVD coloured stainless steel is well used in the architectural and industrial design industry. Examples include;- stainless steel curtain walls, cladding and profiles for hotels and casinos, shopping centres, railway stations and for the facades and fit-outs of high-end retail stores.

The stainless steel’s original texture and structure is not changed however the PVD process not only increases the product’s longevity but also reduces its maintenance. Although it has been used for applications that need to be wear and weather resistant, like door hardware, it is important to say that the colour can be damaged if it is attacked very aggressively and in some instances may not be repairable. PVD lasts longer than other coatings which are a similar thickness.

While angle iron has the surface of other metals, drilling holes through it is quite tricky. Angle iron is made from thin metal sheets with strong surfaces. Drilling in the direction of the fibers also causes the drill to bind up, and you can easily lose control. Follow these steps to drill through the angle iron successfully:

At the smaller end of the scale the coloured steel can be used for anything from display cases, furniture, lighting fixtures, to door handles and taps./p>

PVD coated stainless steel can also be used in the transport industry such as;- ceiling and wall cladding to shipping or seating, skirting and panelling on trains.

For gold and rose gold finish, real gold (maybe 14K or 18K) is evaporated and deposited on the part under high temperatures or via ion bombardment. The shade of the gold achieved is according to the gold content of the target. Colour pigments or gas together with the TiN layer are used to achieve other shades.
