UNI EN 10346 STRUCTURAL
Flat continuous hot dip coated steel products.
This product range is characterised by a layer of surface coating applied via continuous hot dipping of the steel (substrate) inside a solution containing elements that protect the sheet against corrosion.
STRUCTURAL products are carbon-manganese steels with guaranteed minimum tensile strength and yield strength. They have good ductility and are suitable for multiple applications.
• Normal = large regular and bright grain;
• Micrograin = small grain not always visible
to the naked eye
A: Small imperfections are possible such as small alveoli, variations in flower size, dark spots, light scratches and passivation spots.
B: It is obtained through the skinpass. With this type of surface, small imperfections are possible such as scratches due to the skinpass, streaks, irregularities but not cavities.
C: It is obtained through the skinpass. The best surface does not damage the apparent uniformity of a high class of color finish; the other surface must be at least of type B.
C: Chemical passivation; Also available free of hexavalent chromium compliant with the RoHS Directive. The surface may have yellowish residues that do not alter the characteristics of the product.
O: Oiling with oils that can be removed with degreasing solvents. This treatment reduces the risk of surface corrosion.
CO: Oiling + chemical passivation to increase the protective effect against corrosion.
S: Organic passivation, also called AFP (Anti Finger Print) or SPT (Resin Coating), consisting of a polymer film that improves protection against corrosion, avoids the formation of fingerprints, facilitates sliding during processing and behaves from primer in the painting phase.
P: Phosphating, suitable for applying a layer of paint.
PO: Phosphating + oiling to improve formability.
U: Without protection.
The cutting and supply of steel strip from COILS is our “core business”. We process thicknesses from 0.30 to 6.00 mm
Steel strip cutting is Chiminello Srl’s “core business”.
The production process, which has been consolidated by years of experience and improved with ever-more technologically advanced equipment, distinguishes Chiminello Srl as a leading steel strip supplier in terms of quality and product assurance.
The winning feature of Chiminello Srl steel strip is the cutting precision.
Given that the lack of rigidity for dimensional tolerances contained in UNI-EN standards is often a cause of unforeseen events during subsequent customer machining, it is critical that Chiminello Srl supports customers in their actual production needs, supplying a product that goes beyond simple compliance with standards and contributes to the quality of the final product.
The maximum size of metal sheet supply is 2000 x 8000 with a maximum thickness of 6.0 mm (raw, pickled, galvanised or electrogalvanised)
With the recent introduction of a new “cut to length” system, Chiminello has significantly expanded its production capacity in terms of size, quality and productive power.
The manufacture of Chiminello steel sheets is distinguished by the remarkable versatility in terms of size; production is divided into:
Steel sheets standard sizes:
• 1000 x 2000mm
• 1250 x 2500mm
• 1500 x 3000 mm
• 2000 X 4000 mm
Steel sheets special sizes
• Maximum width 2000 mm
• Maximum length 8000 mm
The Chiminello Srl warehouse keeps a stock of standard size material available and ready for collection at the customer’s request.
Chiminello S.r.l. is able to supply steel strap hinges, sheet metal squares and various flat pieces with thicknesses ranging from 0.3 mm to 3.0 mm
The introduction of a new sheet metal levelling and cutting system allows Chiminello S.r.l. to meet the needs of the manual moulding market, light carpentry, small batch machining and non-automated processes.
Correct supply is guaranteed by precise control throughout all machining phases and the product is packaged with special protective coatings against corrosion and rust.
