High productivity is a basic feature of STAM Rollformers, that can allow a quick modification of cross beam dimensions, thanks to flexible devices for changing the forming roll configuration.
The cross beams can be made up in two ways:
using two roll formed profiles which are mechanically fixed and locked to one another;
using a single strip, roll formed to a closed section, with a folded seam or welded, where the two sides joint.
The ends of the cross beam can be attached to the uprights by means of a hook arrangement. The hook connections are fixed to the cross beam ends in two ways:
by bolts (thus the beam is punched during production).
STAM supplies complete production systems for panels for metal cabinets. The material can be in coil or sheet form. Notching, punching or cutting operations are completed before the work piece is passed to the rollformer. The final operations are bending and welding.
The lines are designed for flexibility and high quality of the finished product. The PC system provides the operator with the best combination of reliability and simplicity.
STAM manufactures lines for shelving production.
The shelves can be produced by pre-cut sheet metal blanks or, more usually, coil material, which may be pre-painted or galvanized. Considerable know-how is required to combine quality excellence with reasonable unit cost. STAM equipment can produce up to 15 pieces per minute, and is suitable for different sizes and shapes.
Some different configurations are possible. A basic shelving rollformer can be set up either manually or semi-automatically. With the fully automatic version all the machines are automatically set up, after having entered on the PC both production order and product codes.
Frequently, the rollformers for metal shelving (for example for supermarkets, office cabinets or household applications) incorporate devices to produce stiffening profiles in an integrated system. The stiffening rails are automatically fixed to the shelf by welding or clinching or gluing
STAM is able to supply the complete system for the production of all components of shelving for supermarkets including the floor mounted supporting base, the uprights with the punched holes, the shelves, the shelving clamps, the side panels and the back panels.
STAM is specialist in the supply of manufacturing equipment for supermarket shelves.
Galvanized or pre-painted sheet metal coil is fed into the line which includes sections for initial punching and cutting-to-length followed by the actual roll forming and then final bending and welding. The mounting for the piercing and cut-to-length tools is designed for quick changeovers for different sizes of shelves; the Rollforming machine itself can be changed over for a large number of different sizes of products without involving any manual intervention from the operator.
The lines can be equipped with automatic stacking and packing systems of the finished products.
Microcellular polyurethane foam is the best insulating material and has contributed to revolutionizing a whole range of building system technologies.
STAM has developed and supplied production lines for sandwich panels for cold storage rooms, deep freezer tunnels and refrigerating stores. STAM supplies different kinds of line depending on specific requirements.
Scaffolding is made up of combinations of vertical, horizontal and diagonal members to form a sturdy structure. It is required to pass severe tests in order to obtain safety certification from the relevant authorities.
STAM is able to offer their customers extensive experience for:
Supply of the required Rollforming lines to produce the scaffolding components; assistance in the design of the profiles and the selection of most suitable steel and best mounting solution.
Chequered plates are widely used for flooring or paving applications, heavy duty shelving for pallets and walkways. STAM manufactures production lines for all these products. Before rollforming a press operation is required. Anti-skid features in the form of partially pierced holes and upwardly protruding ribs are formed. The rollformer for folding the desired shape can be designed to enable this forming to be varied both in respect of the width and the height of the profile, either manually or automatically. Design changes depending on the required load carrying capacity.
The slide guide rails must have a high level of accuracy, and in many cases high production rates are required. STAM supplies flexible production lines to manufacture high precision finished products.
STAM builds Rollforming lines incorporating curving facilities for silo panels. The silo is made of corrugated panels of galvanized structural steel. Often the structure is supported by uprights, also made of sheet metal in different thicknesses and in shapes.
The line is capable of rollforming the corrugation and then forming the curve shape with great accuracy. Thicknesses of material can vary from 1.2 to 4 mm. The curving radius can be changed manually using a manual wheel adjustment or automatically using an NC based system. The line includes the piercing section for fitting of other silo accessories. The same section includes the cut out of openings required for silo’s inspection.
