Gun Metal Ingots are high-quality bronze alloy blocks composed primarily of copper, tin, and zinc, designed as the raw material for casting sheets, rods, bushings, and other industrial components. Known for their excellent strength, toughness and corrosion resistance, these ingots are ideal for applications in marine, industrial and engineering sectors. They offer superior wear resistance and excellent machinability, allowing precise fabrication of valves, gears, pump components, bearings and custom-engineered parts.
Gun Metal Ingots retain their mechanical properties under moderate heat and resist corrosion in harsh environments, including seawater and chemical exposure. Supplied in standard rectangular or trapezoidal blocks, typically weighing 5–25 kg each, they ensure consistent alloy composition and reliable performance. With a long shelf life and easy storage, gun metal ingots provide an efficient and flexible solution for manufacturers seeking high-quality raw material for durable and precision-engineered components.

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.
