Supporting the Growth of a Leading Engineering Business
As engineering businesses grow, production equipment must keep pace. Whether demand is increasing, production lines are expanding or new facilities are being developed, manufacturing equipment needs to deliver greater throughput without compromising quality, energy efficiency or safety.
That was the challenge facing B&S Group, a rapidly growing engineering business supporting the UK's power transmission and critical infrastructure sectors.
To increase production capacity and future-proof its manufacturing operation, B&S Group partnered with SurfacePrep UK and Bostec to design and install a bespoke powder coating tunnel oven that integrated seamlessly with its existing production line.
The result is a high-performance curing solution that enables faster production, consistent coating quality and a platform for continued business growth.
The Challenge: Increasing Capacity Without Disrupting Production
B&S Group had reached a pivotal stage in its expansion.
Growing customer demand meant additional manufacturing capacity was essential, but replacing the entire finishing line would have introduced unnecessary cost, disruption and downtime.
Instead, the business needed a solution that would:
- Increase production throughput
- Integrate with the existing conveyor system
- Maintain consistent powder coating quality
- Improve energy efficiency
- Meet modern industrial safety standards
- Support future expansion as production volumes continue to increase
This required far more than supplying an off-the-shelf industrial oven. It called for a bespoke engineering solution designed specifically around the customer's manufacturing process.
The Solution: A Purpose-Built Conveyorised Powder Coating Tunnel Oven
Following a detailed consultation with B&S Group, SurfacePrep UK designed, manufactured and installed a bespoke 10-metre conveyorised powder coating tunnel oven tailored to the site's existing production layout.
Rather than requiring major alterations to the production line, the oven was engineered to integrate directly with the existing conveyor system, allowing the new equipment to become part of the established finishing process.
The finished installation includes:
- Fully insulated double-skinned steel construction to minimise heat loss
- High-performance insulation for improved thermal efficiency
- Integrated gas burner system with automatic electronic ignition
- Continuous burner safety monitoring
- Explosion relief panels built into the roof for additional operator protection
- Precise temperature control for consistent powder coating cure
- Seamless integration with the existing conveyor line
The result is a reliable industrial curing oven capable of delivering repeatable coating quality while reducing operating costs through improved thermal efficiency.
Why Tunnel Ovens Are Ideal for Powder Coating Production
Unlike batch ovens, conveyorised powder coating tunnel ovens allow components to move continuously through the curing process.
For manufacturers processing high volumes of fabricated steelwork or engineered components, this offers several important advantages:
- Increased production throughput
- Consistent curing temperatures
- Reduced manual handling
- Improved workflow efficiency
- Better product quality
- Lower operating costs through improved energy performance
- Greater scalability as production grows
When designed correctly, a bespoke tunnel oven becomes an integral part of the manufacturing process rather than simply another piece of equipment.
The Results
The completed installation has provided B&S Group with a finishing solution designed around both current production requirements and future expansion.
The new tunnel oven has helped the business:
- Increase available production capacity
- Improve process efficiency
- Deliver consistent curing performance
- Reduce heat loss through improved insulation
- Enhance operational safety
- Create a manufacturing platform capable of supporting continued business growth
By integrating with the existing conveyor system, the project also avoided unnecessary disruption while maximising the value of existing production equipment.
ENGINEER INSIGHT
"Every powder coating line is different. Rather than trying to make standard equipment fit, we engineer each tunnel oven around the customer's process, production volumes and future plans. That ensures they achieve the performance they need both today and as their business grows."

Frequently Asked Questions
What is a powder coating tunnel oven?
A powder coating tunnel oven is a continuous curing oven that heats coated components to the required curing temperature as they travel through the oven on a conveyor system. It provides consistent curing, high production throughput and repeatable coating quality.
What are the advantages of a conveyorised tunnel oven?
A conveyorised tunnel oven offers several benefits over batch curing:
- Continuous production
- Higher throughput
- Reduced manual handling
- Consistent curing temperatures
- Improved energy efficiency
- Better product quality
- Lower operating costs
These systems are particularly suitable for manufacturers processing large volumes of components.
Can a tunnel oven be integrated with an existing production line?
Yes. Many tunnel ovens are designed specifically to integrate with existing conveyor systems and finishing equipment, allowing manufacturers to increase production capacity without replacing their entire powder coating line.
Are bespoke powder coating ovens more efficient than standard systems?
A bespoke oven is designed around your specific products, conveyor speed, production volumes and available factory space. This typically delivers better thermal efficiency, improved workflow and more consistent curing than adapting a standard system.
What industries use industrial tunnel ovens?
Tunnel ovens are widely used across:
- Structural steel fabrication
- Architectural metalwork
- Agricultural equipment
- Automotive manufacturing
- Aerospace engineering
- Rail engineering
- General manufacturing
- Power and infrastructure sectors
How do I know if my powder coating line needs upgrading?
Common signs include:
- Production bottlenecks
- Inconsistent curing quality
- Rising energy costs
- Difficulty meeting customer demand
- Ageing equipment requiring frequent maintenance
- Limited capacity for future growth
A production review can identify whether upgrading your curing oven would deliver significant improvements.
