Poland-based BTH Import Stal, has grown into a fast-moving supplier of acid-resistant and stainless steel sheet, coil and tube, and prides itself in being a supplier of added value components to a wide range of customers.
Board member Tomasz Kotarba said: “We are a family-owned business, and our 300 employees are an extension of that family and that makes us special. Unlike many of our competitors, who are simply part of larger shareholder driven corporations, we have the flexibility to respond to market trends. We are also free to invest and invest on an annual basis to ensure that our people and facilities are at the forefront of industry.”
While at the outset BTH Import Stal was a stockholder of stainless steel, the business has evolved to focus more on added value, supplying pre-processed material, semi-finished products, and finished products, such as its Pillow Plate material, which it has developed by ramping up its capabilities with the introduction of laser cutting, bending, and coil processing.
The company currently operates out of a 30,000m
2 facility in Krakow, but has ambitious plans to double that within the next three years, while also increasing the 75,000 tonnes of acid resistant and stainless steel that it processes on an annual basis.
Mr Kotarba continued: “Added value production is becoming a larger part of our business, the more we process, the happier we are. Of course, to achieve this we need to continue to invest, while we are investing in our capabilities, we continue to move forward. While it would be nice to pause at some point, not investing means backward steps, so we will continue.”
Investment based on experienceOver the past 15 years BTH Import Stal has worked on a variety of projects with
Timesavers International, a leading provider of deburring machines and wide belt grinding machines, and the two companies have developed an excellent working relationship.
Mr Kotarba said: “From a commercial aspect doing business with Timesavers is a pleasure, the people are nice, and they are open to do business. Technically, they are also excellent, we rarely have need to contact the service department, but if we do the response is fast and efficient.
“As part of our plans to double the size of the factory, we intend to invest in a second line and Timesavers will be our supplier of choice.”
The relationship has seen a sheet-to-sheet processing line installed in 2007, now fondly known as the ‘Grandma line’ due to its longevity and reliability, as well as stand-alone grinding and surface finishing machines, such as the 42 Series deburring and grinding machine.
The success of these machines and their familiarity in terms of technology made the decision straightforward when BTH Import Stal wanted to increase capacity and capability by introducing a coil-to-coil line.
Mr Kotarba explained: “The Grandma line has been running successfully since 2007 thanks to the solid, yet simple design of the Timesavers machines. The long life of these machines and the fact that in some respects the Timesavers technology is timeless, made the decision an easy one and we probably would not have considered another supplier.”
The new coil-to-coil line features two Timesavers 71 Series machines, one equipped with twin wide abrasive belts for finishing and the second fitted with twin brushes for fine finishing operations. The decision was founded on improving efficiency and productivity.
Both Timesavers 71 series machines can operate independently, depending on the surface finish specified by the customer, and subject to the thickness of the material, a coil can contain up to 1.5km of stainless steel, which can be processed without interruption or manual intervention.
Mr Kotarba added: “Processing coil material is much more efficient than sheet-to-sheet both in terms of throughput and production costs. Consumable costs are reduced as we find the abrasive belts last much longer, and the productivity gains we can achieve will see costs reduced by 50% in some cases.”
Both machines are operated under ‘wet’ conditions, with the abrasive belts and material subjected to coolant delivered at every stage. Therefore, a washing/drying unit is installed in the line prior to the material be re-coiled.
Using a wet process may seem out of step with modern environmental thinking, but Mr Kotarba disagrees: “Wet grinding is often viewed as old technology and less friendly to the environment, but we see it as having distinct advantages in the manufacturing process.
“We can achieve better and more consistent finish on the material we are processing when grinding with coolant, this is a particular advantage when processing coil. It also reduces the number of abrasive belts that we use compared to dry grinding, which is a positive outcome in environmental terms.”
Tried and tested technologyThe Timesavers 71 Series are highly versatile machines able to be configured with either two abrasive belts or twin brushes. They can be adapted to work on sheet or coil material in three standard widths, which are 1,350, 1,600 and 2,100mm with a material throughput rate of up to 30m/min.
They are capable of producing a variety of surface finishes including Duplo, Microlon and Hairline in stainless steel materials and control is via an easy-to-use Siemens man/machine control.
Conveniently located at a good working height and position, the operator can control every aspect of the process, while maintaining a good line of sight to the material being fed into the machine.
Mr Kortoba continued: “The versatility of these Timesaver machines ensures that we can meet the demands of our existing customers, across a wide range of industries, including existing customers ranging from major manufacturers through SMEs and business to consumer clients across a range of sectors including architectural, medical, food processing and construction.
“The investments we have made have created a flexibility that our competitors are unable to match and that is something that is appreciated by customers, who are confident that we can deliver on our promises. We are focused on providing customers with a first-class service and our can do attitude, means a customer will never hear us say ‘we can’t do that’ — we will constantly strive to meet their requirements.”
Investment in systems and manufacturing capability, such as the Timesavers coil-to-coil line is evidence of BTH Import Stal’s philosophy of being open with customers, with family members always accessible for discussions.
Mr Kotarba concluded: “Our focus is on the customer not the shareholder, we operate as a family business and I think this is what makes us special.”
Timesaver machines are available in the UK and Ireland from Christchurch-based
Ellesco Ltd, a leading supplier of deburring, polishing and finishing machines.
