Bright steel bars for dependable machining and industrial supply
More than 40 years of experience in steel-bar supply. Send the grade, size, quantity, and delivery location to start a clearer material check.
Three ways we support better buying decisions
CV Tanamas does more than list material. We help buyers frame a request around the grade, form, dimensions, and delivery needs that matter to production.
Documented quality
Supported by the quality documents named in our company materials, with Mill Test Certificates (MTCs) available by batch where applicable.
A practical size range
Round, hexagonal, square, and hot-rolled bar options help buyers match shape and size to their process.
Responsive coordination
Share the specification, quantity, and delivery location so the sales team can help check the relevant supply path.
Buy with a specification, not a guess
A steel-bar enquiry becomes easier to assess when it starts with the component or process it must support. A shaft, bushing, fastener, bracket, or fabrication part may require a different combination of grade, shape, surface condition, and size.
Before asking for a quotation, identify the applicable drawing or standard, the desired grade or acceptable equivalent, the material form, the working dimension, total quantity, and delivery point. This gives the sales team the context needed to check the right option rather than simply compare a price per kilogram.
- State the intended application or production process
- Name the grade or the performance requirement behind it
- Include the diameter or section size and quantity
- Ask what document and lead-time confirmation is available for the proposed order
Choose the profile that reduces unnecessary work
Round bar is commonly selected for shafts, pins, rollers, bushings, and other cylindrical components. Hexagonal bar can reduce initial shaping for nuts, couplings, fittings, and components with wrench flats. Square bar is useful for blocks, brackets, guides, jigs, and key-stock applications.
The suitable profile is not only a design decision. It affects cutting, turning, milling, setup time, material yield, and the amount of machining required before the part reaches its target geometry.
Confirm the order-critical details before release
Material names and grade labels are useful starting points, but the purchase order should still be checked against the applicable standard, dimensions, condition, and documentation requirement. Where a Mill Test Certificate is required, ask for the traceability process and confirm that the certificate corresponds to the delivered batch.
This approach keeps the conversation practical: match the request to the component, verify the commercial and technical details together, then proceed with a written order scope.
Industries we support

A versatile form for machining, shafts, and cylindrical machine components.
Hexagonal bar
An efficient profile for nuts, couplings, fittings, and keyed parts.
Square bar
A square profile for blocks, brackets, key stock, and jigs.
Frequently asked questions
What information should I send for a steel-bar quotation?+
Send the grade or required standard, form, diameter or section size, quantity, delivery location, and any drawing, tolerance, or certificate requirement that affects the order.
Can CV Tanamas help if I only know the component application?+
Yes. Describe the component, production process, working environment, and known dimensions. The final material decision should still be approved against your engineering specification.
Is an MTC included automatically?+
MTC availability should be confirmed for the relevant grade, batch, and order. Ask the sales team to include the documentation requirement in the quotation or purchase order discussion.
