Product Detail
Product Introduction
Titanium perforated sheet is made from solid titanium sheet with holes produced by an agreed punching, drilling or laser-cutting route. It retains continuous ligaments and can include solid borders, unlike slit-and-stretched expanded metal. A purchase description is incomplete until the titanium grade, raw-sheet specification, sheet thickness, finished hole size, center-to-center pitch, row pattern, perforated-field location, margins, panel size, burr direction and finished flatness are defined.
How should a titanium perforated sheet be defined?
Selection answer: Start with the finished panel: grade and raw-sheet standard, thickness t, hole shape and finished diameter d, center-to-center pitch p, straight or staggered rows, perforated-field limits, solid margins, overall size, burr direction and flatness.
Selection boundary: Hole diameter or open area alone does not define the panel. The feasible hole-to-thickness relationship, ligament, manufacturing route and distortion control require drawing review; the common ranges on this page are not inventory or unconditional manufacturing promises.
RFQ data to confirm: Send a dimensioned drawing or perforation schedule, quantity, service medium, required inspection, surface condition and the exact material-standard revision.
Selection Priorities
Hole pattern and open area
State round, square, slot or drawing-specific holes; finished hole size d; pitch p; straight or 60° staggered rows; minimum ligament; target open area; and pattern orientation. For round holes in a 60° staggered, fully perforated field, theoretical OA (%) = 90.69 × (d/p)² when d and p use the same unit.
Margins and finished panel
Define the perforated-field origin, solid edge margins, unperforated zones, cut size and allowable edge condition. The field formula excludes margins, so finished-panel open area may be lower.
Processing and flatness
Agree punching, drilling or laser cutting after reviewing thickness, hole size, quantity and edge quality. State burr direction, deburring, surface condition, post-perforation flatness and any forming or welding after perforation.
Product Specifications
| Product | Titanium Perforated Sheet | Grade | Titanium Grade 1, Grade 2, Grade 7 or order-specified alloy |
|---|---|---|---|
| Standard | ASTM B265/B265M-25 is the primary current American raw-sheet material reference; ASME SB-265 may be invoked for applicable projects. ISO 7209:2023, GB/T 3621-2022 and JIS H 4600:2012 can be reviewed for international enquiries when the exact grade, product form, condition, edition and tests are stated. EN/DIN or GOST requests must likewise identify the exact document and revision. These systems are not automatically equivalent. None of these raw-sheet references alone defines finished perforation: the approved drawing or perforation schedule controls holes, pitch, pattern, margins, open area, burr direction, flatness and acceptance. | Size & Form | Common RFQ references: 0.5–6.0 mm thickness, 0.5–20 mm finished hole diameter and 1,000 × 2,000 mm panel; exact combinations require drawing and process review and are not stock statements |
| Tolerance | Approved-drawing tolerances for thickness, hole size, pitch, pattern location, ligament, margins, cut size, burr, flatness and surface | Supply Condition | Cut panels or drawing-specific parts, perforated and deburred by the agreed route, with surfaces and edges protected for transport |
| Inspection | Review raw-sheet identity and heat/lot traceability, thickness t, finished hole size and shape, pitch p, row pattern and orientation, perforated-field location, solid margins, minimum ligament, open area when specified, burr direction, deburring, panel dimensions, flatness and surface condition against the approved drawing and sampling plan. | Documents | Product test certificates can be provided. |
Additional Supply & Ordering Details
Useful, technically consistent information consolidated from earlier product pages.
| Perforated vs expanded | Perforated sheet removes material to create controlled holes while retaining solid ligaments and optional borders. Expanded metal is slit and stretched into strands and bonds; the two forms are not interchangeable. |
|---|---|
| Open-area formula boundary | For round holes in 60° staggered rows, the common theoretical field formula is OA (%) = 90.69 × (d/p)². It applies to the repeating perforated field, not solid margins or unperforated zones. |
| Common-size boundary | The thickness, hole and panel values shown above are common RFQ references only. Availability and the feasible hole-to-thickness, ligament and flatness combination must be confirmed for the drawing, quantity and selected process. |
| Photo evidence boundary | The owner-branded photograph confirms physical perforated-sheet examples on the right side. Grade, dimensions, standard compliance and inspection results cannot be determined from appearance. |

Services We Can Provide
Product Packaging
Sheet and plate surfaces are interleaved or wrapped as required, protected at edges and secured on pallets or in export cases with grade, heat and dimensional identification. Typical export packaging for the same physical product form is shown below; final packing is confirmed for each order.
Application Scenarios
Flow distribution and support screens
Hole pattern, open area, pressure drop, support spacing, flatness and edge restraint must be matched to the equipment design.
Chemical-process trays, guards and separator internals
Service chemistry, temperature, solids loading, drainage, cleaning, joining and solid-margin layout require project review.
Electrochemical electrode or current-collector panels
Grade, surface preparation, current density, electrical connection, contact resistance and process chemistry must be defined by the electrochemical design.
FAQ
How is titanium perforated sheet different from expanded titanium metal?
Perforated sheet removes material to form holes and retains solid ligaments and optional margins. Expanded metal slits and stretches sheet into strands and bonds without punching out holes.
How is open area calculated for 60-degree staggered round holes?
For a fully perforated repeating field, theoretical open area is OA (%) = 90.69 × (d/p)², where d is finished hole diameter and p is center-to-center pitch in the same unit. Solid margins and unperforated zones reduce finished-panel open area.
Is hole diameter enough to request a quotation?
No. Also state sheet thickness, pitch, straight or staggered pattern, perforated-field limits, margins, panel size, minimum ligament, burr direction, flatness, quantity and inspection requirements.
Should titanium perforated sheet be punched or laser cut?
The route depends on thickness, hole size, ligament, quantity, edge-quality requirement, distortion risk and tooling. Confirm the route only after the drawing and acceptance criteria are reviewed.
Which standard applies to titanium perforated sheet?
ASTM B265/B265M-25 or another expressly invoked standard can control the raw titanium sheet. The finished holes, pitch, margins, open area and flatness require an approved drawing or perforation schedule.
What documentation can be supplied?
Product test certificates can be provided. State the required material, heat/lot, dimensional and inspection records in the RFQ.
