Gun Metal Plates are superior bronze alloy plates made out of a copper, tin and zinc mixture, which have good strength, wear resistance and corrosion resistance. Various applications of these plates are in the engineering and industrial sectors, where a high degree of reliability and durability is very necessary. Gun metal plates are good for load bearing as well as performing in environments of friction and pressure as well as constant mechanical forces. They are very resistant to corrosion due to water, steam and mild chemicals and can therefore be used in marine, pump and valve applications.
Gun Metal Plates are easily cut, drilled, milled and fabricated into modified plates, including wear plates, guide plates, spacers, liners and bearing parts, due to their good machinability. Usually applied in the automobile sector, industrial machinery, electrical and fabrication, gunmetal plates are used to increase equipment service life by lowering wear and maintenance. They come in different strengths and sizes and provide a reliable and economical, heavy-duty and precision-engineered solution.
Ganga R Ispat Metals Gunmetal Plates Manufactures in India that are used in demanding industries that demand high load bearing, corrosion resistance and long service life in the demanding conditions of operation. We produce Gunmetal Plates through tightly monitored alloy melting, casting, rolling and stress relieving procedures to produce a smooth structure and reliably consistent mechanical behaviour. Each plate is tested in terms of chemical composition, hardness test, dimensional check, and surface quality check, utilising our state-of-the-art in-house laboratory equipment. Gunmetal Plates are used extensively in marine equipment, pumping assemblies, valve components, bearing housings, and heavy engineering systems where the failure of the material is unacceptable.
The use of Gunmetal Plates in India is in instances where there is continuous contact with fluids, a change of pressure, and mechanical strain. Our plates have great resistance to both corrosion and are machinable with good performance in salty and industrial conditions. Our Gunmetal Plates come in standard thickness selections and also in custom sizes, which means that they can be used in fabrication processes like machining, drilling, and surface finishing without deformation. Our plates are needed by engineering firms and OEMs where structural reliability and material integrity are vital.
We are the Gunmetal Plates Suppliers in India, and we are concerned with a stable supply, specifications and reliable delivery times. Before dispatching, each plate is tested in a market plate spectrometer, a hardness test, a thickness test and a visual inspection. With our built-in manufacturing strategy, we guarantee batch-to-batch consistency, dimensional consistency and predictable machining behaviour.

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.
Gunmetal plates are suited for precision work. They have good machinability and dimensional stability, which enables the accurate cutting, drilling, and shaping. They provide a pleasing surface finish. Augmenting the work to be done.
Gunmetal plates are dependable under pressure, wear and demanding engineering and fabrication. They are consistent in quality and provide strong mechanical properties and a stable alloy composition.
Gun metal plates have a service life and lose the oxidation and corrosion to moisture, chemicals, and environmental factors. They require less maintenance and have surface integrity.
Strength comes from the alloy's composition. This gives the plates high mechanical strength and reliable performance under pressure and continuous load conditions.
Gun Metal Plates are commonly used in valve components, pump parts, marine fittings, bearing plates, and heavy engineering applications due to their high strength, wear resistance, and corrosion resistance.
Gun Metal Plates are available in grades like LG2, G1, G2, and G3 (BS 1400 standards), offered in various thicknesses with custom cut sizes for industrial and export requirements.
