A 211 beer can bottom end is a can-end format identified by a nominal diameter designation of 2 11/16 inches, or approximately 68.3 mm. That number is a useful starting point, but it does not by itself confirm that an end will run on your can body or seaming equipment. Buyers should verify the end profile, curl and countersink dimensions, material, coating, and seaming requirements against an approved drawing and production trial. This guide explains what to check before selecting and sourcing 211 beer can bottom ends.

This guide is intended for breweries, beverage-can manufacturers, packaging procurement teams, and distributors evaluating 211 beer can bottom ends. It is especially useful when qualifying a new supplier, introducing a new can format, or checking whether a proposed end can work with an existing line. The final selection should be confirmed by the parties responsible for the can body, end, and seaming process.
Packaging terminology and measurement conventions can differ between suppliers and markets. Treat product descriptions as a screening tool, then use the supplier’s drawing and your own equipment requirements to confirm the order specification. If you are replacing an existing end, share the current part number and approved technical documents where available.
A can bottom end is the formed closure fitted to the lower end of a compatible can body. It contributes to package integrity and must form a reliable seam with the body during can manufacture. In a beer package, the bottom end is one component of a system that also includes the can body, the top end, coatings, and the manufacturing and filling processes.
The “211” designation is commonly used for a nominal end size of 2 11/16 inches. Converted using 25.4 millimetres per inch, this is approximately 68.3 mm. Do not assume that this nominal figure describes every critical formed dimension or that all products labelled 211 have identical profiles.
Suppliers may specify additional measurements, tolerances, profiles, and product codes. Ask which measurement the designation refers to in the supplier’s system and request a current drawing before approving a part. That step helps prevent a nominal-size match from being mistaken for full mechanical compatibility.
Beer can ends are commonly supplied in aluminum formats, but material and coating details should be verified for each product rather than assumed from the application. The material affects forming and seaming behavior, while the coating system is selected in relation to the package and its intended use. Confirm that the proposed end is designed for your beverage packaging requirements and process conditions.
The correct bottom end must fit the can body and seaming system as a matched package. A 211 end may be appropriate for a project only when the body dimensions, end profile, tooling, and line settings are compatible. If your current line is configured for another end size or profile, a change may require equipment assessment and trials rather than a simple component substitution.
Request a technical data sheet and drawing that identify the specific product being quoted. The following points give procurement and engineering teams a practical comparison framework. If a value is critical to your process, agree on its measurement method, tolerance, and acceptance criteria with the supplier.

| Specification area | What to verify | Why it matters |
|---|---|---|
| Nominal size and profile | 211 designation, drawing revision, and formed-end profile | Confirms that both parties are discussing the same end configuration. |
| Critical dimensions | Relevant diameters, curl, countersink, and stated tolerances | Dimensions influence fit, handling, and the seam formed with the body. |
| Material | Material description and any agreed material requirements | Supports assessment of forming, process compatibility, and specification compliance. |
| Coating and finish | Exterior and product-contact coating details, where applicable | Helps confirm suitability for the intended package and storage conditions. |
| Quality documentation | Inspection plan, lot identification, and available product records | Clarifies how conformity and traceability will be managed. |
| Packaging and logistics | Pack format, protection, order quantity, and delivery terms | Reduces handling and supply-planning surprises after approval. |
Before requesting a quotation, ask whether the proposed end is intended for your exact body and seamer configuration. Confirm which dimensions determine fit, what sample and trial support is available, and how production lots are identified. If you are changing suppliers, compare the new end against your approved reference rather than relying only on a product description or nominal size.
Quoted pricing can depend on order volume, product configuration, material and coating requirements, packaging, and delivery destination. Minimum order quantity and production lead time are supplier- and order-specific, so they should be confirmed in a written quotation rather than assumed from the 211 designation. Ask whether samples, production orders, and repeat orders follow different commercial terms.
For a fair comparison, request quotations using the same specification and delivery basis. Include the drawing revision, required quantity, destination, target delivery window, and any documentation or packaging needs. Consider freight, inventory planning, and the cost of a qualification trial alongside the unit price.
Strong supplier evaluation is about more than confirming that a product is described as 211. Buyers need a clear route from drawing review to sample approval, production planning, and repeat-order control. Keep the approved specification accessible to purchasing, quality, and manufacturing teams so subsequent orders can be checked against the same requirements.
Wanhua supplies packaging products and can work with B2B buyers evaluating beer can bottom ends. Share your target 211 specification, body and equipment requirements, estimated demand, destination, and timing so the proposed product and commercial details can be reviewed against your project. Where a detail has not yet been confirmed, identify it as an open point rather than treating it as an agreed specification.
When contacting Wanhua, include an existing drawing or part reference if available, along with any required sample or documentation needs. Our team can discuss product specifications, order planning, and export arrangements for your inquiry. Final compatibility should be established through technical-document review and an agreed production trial before full-scale adoption.
A 211 beer can bottom end is identified by a nominal size commonly expressed as 2 11/16 inches, or approximately 68.3 mm, but that designation alone cannot establish compatibility. The dependable route is to confirm the full drawing, material and coating details, body fit, and seamer requirements, then validate the selection through an agreed trial. This protects the project from avoidable specification misunderstandings and supports a more controlled purchasing decision.
Your next step is to prepare the current body and equipment information, define the required order quantity and delivery window, and request a written specification and quotation. Contact Wanhua with those details to begin a focused review of 211 beer can bottom ends for your packaging application.
