Gun Metal Sheets are superior bronze alloy products manufactured using predominantly copper, tin and zinc, giving them a perfect combination of strength, endurance and resistance to corrosion. Gun metal sheets are known to have high wear resistance and good machinability, which makes them highly applicable in engineering, marine and industrial sectors. They can operate in very difficult conditions such as seawater, steam and chemicals leading them to be extremely useful in the form of valves, pump components, bearings, gears, bushings and decorative hardware.
Gun metal has a good load-carrying capacity and dimensional stability, which guarantees a long service life and a constant performance. The use of these sheets is due to the finish of the surface, corrosion resistance, and the capacity to endure moderate mechanical stress. Gun metal sheets come in different thicknesses and sizes in accordance with industry standards that can be precision machined and custom fabricated. They are used in preference in situations that require strength, resistance to corrosion and reliability.

Packaging is a major part of every delivery, and we understand it very well. We supply many types of metals and other industrial metal products to make sure they reach our customers safely. We know products face many types of problems, such as vibration, moisture and rough handling therefore we follow a careful and organised packaging process. Our goal is simple: we deliver every product in the same strong and perfect condition as when it leaves our facility.
We check every order before packing it. The size, straightness, surface quality, grade, and quantity of each rod and bar are checked. We ensure that the material is correct as per the customer request. Once inspected, we sort the products by their size and grade of material. This will ensure that we maintain the order in everything and prevent errors in dispatch. Bundling and loading are also simpler and quicker.
After these steps, make sure to arrange the products in proper alignment so that they are straight and balanced. Then they are strapped down with industrial grade strapping. These straps keep the bundle secure during lifting and transportation. We include additional support to shorten bending or movement in longer rods. We also ensure that the straps do not tear the edges or the surface of the material. This cautious wrapping ensures the merchandise is secure throughout the delivery and transportation.
Sometimes metal can be damaged by moisture and changing weather conditions. We apply protective methods based on the shipment type and destination. We may use anti-rust coatings, moisture-resistant wrapping, or protective covers to prevent them. Our additional cover against humidity and corrosion is given to export shipments and coastal deliveries. These will assist us to retain the shine, surface finish and integrity of our metal products in the long-distance transportation.
In case of large orders and/or shipments to the export market, we offer extra protection. We pack them on heavy pallets or stuff them into tough wooden structures that can be transported all over the world. The packaging is dependent on the size and weight of the shipment. We ensure that the packing is able to withstand packing pressure and movement of containers. This strong outer coating secures the materials throughout their long trips, port services and storage in warehousing.
We have proper lifting equipment such as forklifts and cranes to load materials. Our team places the bundles carefully inside trucks or containers. We place them in such a manner that they do not roll or shift during the transportation. We balance the weight to minimise the weight on any section of the shipment. Our safe loading methods give us the chance to reduce the chances of being damaged in transit, whether it is along the road or the sea.
Ganga R Ispat Metals distributes its products in India and also in overseas markets. We provide transportation with trusted logistics vendors. In the case of domestic deliveries, we organise road transportation. In export orders, we meet the international shipping standards and container loading requirements. Each shipment will be planned based on the delivery schedules to make it arrive on time. Our well organized transport system assists us in delivering products in an efficient and safe way.
We make ready all papers preceding dispatch. These documents can be invoices, packing lists, and required certificates. Proper documentation assists in easy transportation and reduced time in clearance of customs when making export shipments. We have good records to promote transparency and professional service.
A well-structured packaging and transportation process directly impacts product performance upon delivery. Our approach ensures:
We believe that packaging is not just about wrapping materials — it is about protecting the value and reliability of the product until it reaches the client.
In Ganga R Ispat Metals, we suppose that safe packaging and transportation ensure the value of our products. To avoid bending, scratches, and corrosion, we make every effort to avoid transit damage. We consider packaging as our quality responsibility. We have a standard process; however, our packing techniques are changed according to the product size, order quantity, and destination.
We ensure that all the rods and bars are sold to our customers in a powerful, secure and working condition. We offer secure packaging or assured transportation as an additional service.
Yes, gunmetal sheets provide great resistance to corrosion particularly in water and steam, as well as in marine conditions. This renders them applicable in applications that are subjected to moisture, chemicals and severe operating environments.
In marine fittings, marine valves, marine bearings, pump parts, bushes, gears and industrial parts, it is commonly applied in gunmetal sheets to provide resistance to corrosion, pressure, and wear necessary to ensure long-lasting performance.
Gunmetal sheets are made of alloy sheets of copper, which are mainly made of copper, tin, and zinc, with traces of lead. They are characterised by high levels of strength and resistance to corrosion in harsh industrial conditions.
Yes, the gunmetal sheets may be delivered in accordance with the international standards of IS, ASTM, BS, or DIN, and also to customer-oriented drawings and technical specifications.
There is a variety of standard sheet thicknesses and sheet sizes in gunmetal. Specific customer or project requirements can also be fulfilled, whether it is a custom thickness or a cut-to-size sheet.
Yes, our gunmetal sheets are produced to the export standard and those are packaged in protective and moisture-resistant materials to make sure that they are transported safely abroad.
