Rostfrei has come up with a new technology which increases the longevity and makes the cable tray resistant to shock. The material used for the manufacturing of cable tray is Glass-Fused-to-Steel. The steel is fused with glass enamel to increase the properties of steel.

These tanks are fabricated using the highest grade of Zincalume Steel as MOC, which lasts up to four times longer than galvanized steel. We use our vast industrial knowledge experience in continuous up gradation of latest software technologies to acquire supreme designs, execution capability and techniques. ROSTFREI efficiently proffers a wide product line to its global customers as per their specific requirements at highly competitive prices. Zincalume steel, a premium material complies with requirements of Indian Standard IS 15961, International Standard ISO 9364, Australian Standard AS 1397 and American Standard ASTM A 792M. Zincalume steel is manufactured by a continuous hot dipped metallic coating process. The alloy coating of Zincalume steel provides excellent corrosion resistance and has been found to possess greater resistance to cracking and peeling. Zincalume steel has an alloy coating of 55% Aluminium, 43.5% Zinc and 1.5% Silicon. The 150g/m2 (with option of 200g/m2) coating weight is distributed equally on both surfaces of the coated strip. Metallic surface is coated with separate layers of special passivation solution and resin.

Rostfrei Steels Zincalume colorbond tanks is one of the worlds most advanced prepainted steel products for the building and construction industry. Rostfrei tanks are capable of withstanding extreme environmental conditions, ultra-violet radiation, humidity, and gives long lasting support. Rostfrei Zincalume colorbond tanks are available in standard colours & as per special requirement with a Possibility of your exclusive colour with 150 g/m2 (AZ150) metallic (55% Al-Zn alloy) coating and Lead free paint system of Super Durable Polyester & Inorganic Pigment, is designed for exterior environment and conforms to AS/NZS 2728 Type 4 & ASTM A 755M. Rostfrei Zincalume colorbond tanks have longer life, excellent anti-corrosion performance, superior aesthetics with Gloss retention and much delayed chalking.

Rostfrei Steels PVC Reinforced liner Tanks are suitable for storage of a large range of liquids. Rostfrei Liners are tested for 4 lakh folds for any crack. Rostfrei liner based tanks are US-FDA certified and are safe to store water in any environment condition. Rostfrei Steels has earned an expertise in fabricating and engineering steel structures like liquid storage tanks in multiple dimensions.

SS / FRP SMC PANEL TANKS:

GLS tanks are Glass Lined Steel tanks, also known as Glass-Fused-to-steel tanks. The reason of fusing glass with steel is to enhance the properties of latter. Single Steel is vulnerable to environmental conditions, hence the fusion is required. After fusing the steel with glass, the strength increases, the acceptable bracket of PH value for alkaline solutions widens, and the resistance of abrasion inflates.

Process and Technology:

The tank panels are lined inside and outside with the glass enamel. The enamel is a solid, smooth and shiny cover of silicate. It is fused in a special furnace having temperature ranges from 780 to 900 degree Celsius. The Steel rounded (cylinder) shell of the tank is built from two-layer glass-fused sheet coated on both the sides. The sheets are attached with special high-grade bolts and sealed by constantly flexible silicones (sealants). The connecting material and shell accessories are equipped with the surface treatment. The glass-fused tanks can be used to store fluid or loose material. The tanks are also a fundamental building element of environmental technological facilities such as Waste Water Treatment, and Biogas Stations.

Quality Assurance and Standards:

Every sheet is checked in the manufacturers plant for the enamel layer completeness by using the POROSCOPE (DEZ 4.13) and PINHOLE (DEZ 4.12) test according to DIN ISO 2746. The chemical resistance and physical properties are also tested according to DIN and they comply with the highest quality requirements according to the methodology by the German Enamellers Association (DEZ).

Characteristics of Rostfrei Glass-Fused-To-Steel Tanks:

• Glass-Fused Tanks serve for more than 40 years.
• Abrasion and Chemical resistance is quite high.
• Construction methodology is very quick and safe.
• A pre-built tank is easily relocatable.
• Ecologically safe.

Rostfrei design and manufacture chain conveyors, screw conveyors and belt conveyors for different applications to meet operational needs.

Chain conveyors are equipped with high quality component and are ideal for horizontal and inclined conveying of products demanding a completely closed dustproof transport such as grain, pellets etc. Rostfrei chain conveyors are designed in a modular system and be supplied in exact required length with different capacity ranges from 2TPH to 1000TPH. They are available with various accessories making them suitable for special applications, and with additional features which raise the level of safety.

Screw conveyors are designed for competent and consistent transport of a wide range of agricultural and industrial products. Equipment and accessories are manufactured both for straightforward conveyors and for complete systems for large turn-key projects. These conveyors are constructed with reversible motors and several gate-controlled, bottom dump discharge points to provide flexibility.

Belt conveyors are used for moderate horizontal conveying of granular products like grains, pellets, powder etc. The shape of the belt , system inclination and speed of movement are dependent on the solids content and consistency of the material. Typical speed of belt conveyor is 11-16 km/hr.

Rostfrei slide gate valves are designed to stop grain flow from outlets of storage bins, silos and other discharge point. Slide gates are available in manually actuated and pneumatic slide gate valves. The standard sizes are available in standard size ranging from 6inch to 36 inch.

Bucket Elevators are used for transporting flowable bulk material vertically. Rostfrei Bucket Elevators are designed in such a way that withstand easy mechanical process with high quality components. A bucket elevator can elevate a variety of bulk materials from light to heavy and from fine to large lumps.

Pre Cleaner is used to remove the particles other than the grain, like dust, straw, sand, clay, etc.

sweep auger is used in silos with flat bottom to unload the rests of the grain inside the silo; the auger collects the material inside of the silo rotating into 360 degreesand directs the material towards discharge openings located on the unloading auger.
