ERW Steel Pipes Usage
Used for low pressure liquid delivery, such as Gas, Water, Sewage and Oil.
ERW Steel Pipes Packaging & Shipping
Packed ERW Steel Pipes
Packed ERW Steel Pipes
Plastic closes both ends, Hexagonal bundles maximum 2.000 kg with several steel strips, Two tags on each bundle, Wrapped in waterproof paper, PVC sleeve, and IN in sackcloth with several steel strips, Plastic caps.
Both ends of each crate will indicate the order no., heat no., dimensions, weight and bundles or as requested. We can also offer customized packaging for ERW Steel Pipes as per customer's requirement.
Overseas Packaging
Export packaging is geared towards the protection, handling and transport of ERW Steel Pipes by air or sea freight and, as such, shares many characteristics with export and transport packaging. Utmost care must also be taken to make overseas packaging suitable for long periods of storage. It is important for overseas packaging to be designed with ease of handling in mind, so as to ensure ERW Steel Pipes is treated with the utmost care at all times.
