Introduction to Kalup
Kalup is a recognized manufacturer in the steel pipe and profile market, focusing its production on four primary categories: water pipes, spiral pipes, well casing pipes, and industrial profiles. This diverse product range allows the company to serve various requirements across construction, water supply, and industrial infrastructure projects.
Products, Dimensions, and Standards
The listed products from Kalup are manufactured according to the ST37 standard. This steel grade is widely used in structural applications and transmission networks due to its balanced mechanical properties and excellent weldability. The product catalog includes:
- Water Pipes: Primarily used in urban and rural water transmission and distribution networks.
- Spiral Pipes: Suitable for large-diameter transmission lines and infrastructure projects such as water and sewage systems.
- Well Casing Pipes: Designed for lining water wells to prevent wall collapse and maintain the pumping path.
- Industrial Profiles: Extensively used in steel frames, industrial structures, and general construction (including dimensions such as 140140 and 200200).
Available sizes in the catalog range from 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 24, 28, 30, 32, to 36. Thicknesses available include 5, 6, 8, 10, 12, 16, 20, and 24 mm. Please note that not every size and thickness is available across all product categories; availability must be verified for each specific product.
Buying and Selection Guidance
When selecting products from Kalup, consider the following guidelines:
- Specification Matching: Since applications range from water transport to well casing, buyers must ensure that the ST37 standard and the chosen thickness match the technical requirements and operating pressures of their specific project.
- Weight Calculation: As pricing is based on weight (per kg), the weight per length varies significantly across different sizes. To accurately estimate the final cost, verify the weight per piece and the total number of pieces required.
- Inventory Verification: Given the wide range of sizes, confirm the availability of the specific size and thickness within the desired product category before placing an order.
- Logistics Coordination: Coordinate the minimum order tonnage and loading location with the sales department to ensure transparent transportation costs.
Prices include VAT by default. Each product’s pricing unit is shown in the table.
