“Finding a Better Way” isn’t just a tagline at Rosler Metal Finishing; it’s a mission. A recent preservation line developed by Rosler Germany is no exception.
The creation of a 740-foot-long (225 meters) shot blasting line with straightening equipment is the largest equipment project Rosler Germany has ever undertaken. Commissioned by Meyer Shipyard in Turku, Finland, the state-of-the-art equipment will be used to prepare and finish materials for building cruise ships.
Shot blasting machines come in all shapes and sizes. Selecting a machine capable of cleaning and descaling complex fabricated components and welded constructions is not a task to pursue alone. Seeking the help of a company with proven expertise in the shot blasting field is always advised.
Designed specifically to clean wide head and base plates, ribs, re-enforcements, and the welds from fabrication, shot blast machines, such as roller conveyor machines, are designed around these types of work pieces.
These machines are capable of cleaning and descaling complex welded fabricated components and constructions. They are designed specifically to clean wide head and base plates, ribs, re-enforcements along with the welded seams after construction.
All round blasting is achieved after 3D simulation and actual placement of the blast wheels in the optimum locations of the blast chamber. The chamber can be designed with 2 blast zones, each zone designed to blast clean the surface of the infeed side and the second, the outfeed side and end. As the fabrication passes through the chamber, all gussets, re-enforcements, ribs, angles are descaled and cleaned to Sa Swedish standards and with the desired profile to optimise the adhesion of the coating to be applied.
The equipment requires to easily meet the most stringent customer specifications regarding surface cleanliness and cost, for steel traders, steel fabricators, equipment manufacturers, shipyards and manufacturers of wind power stations. In wind power applications roller conveyor systems are utilised for shot blasting of the steel sheets or plate required for the fabrication of the towers for off-shore and land based windmills.
Typical applications fall into these fabricating industries:
Partners for Steel
There are distinct benefits to be offered by the cooperation between the manufacturers of both shotblast equipment and multispindle drill/saw lines. The objective of cooperation (as partners for steel) is to support customers in resolving the interface problems between the various technologies, integrating shotblasting, measuring, marking, drilling and sawing or punching and shearing or coping and profiling thereby offering customers added value and profit from the processing of steel.

Steel trading companies and fabricators shot blast their steel plate, sections and pipes to achieve a degree of surface cleanliness that is required before protective coatings are applied or other surface preparation needs.
Automated roller conveyor shot blast systems offer solutions which guarantee a highly-efficient descaling, rust /oxidisation removal and general surface cleaning of all kinds of steel.
Shot blasting is a process for the surface treatment of plate, pipes, beams, tubes and bars.
Due to the design, roller conveyor shot blast systems are ideally suited for this application as it allows fast and highly-effective cleaning and surface preparation and at the same time, provides the surface with a profile to which a coating will adhere well, accommodating a wide- range of commercial to marine offshore standards.
The equipment descales the surface of the steel ready to accept a first-class coating, or further engineering processes.
Equipment design and efficiency are paramount and should include the following as basic design and inclusions;
Generally, standard equipment concepts allow the processing of components from 1000mm wide, upto 5200mm wide and 600mm high. Other configurations may be offered as bespoke equipment and to accommodate more complexly designed fabrications.

The demand for pre-finished quality steel sections, plate and tube is increasing throughout the world, year on year. Many steel stockholders, distributors, fabricators and shipyards require their steel to be brought to the highest standard of cleanliness and coated for corrosion protection.
Shotblasting of steel plate, profiles, construction, and fabrications is a process to clean, descale, provide a specified surface profile and edge break as a surface preparation. The process detail is subject to the hardness and start condition of the steel and it is vital to know these factors prior to shotblasting and before application of a coating or paint to maximise the adherence potential and corrosion control.
