QEEHUA reviews large polypropylene sheets and extra-thick PP sheet requirements for fabricated tanks, scrubbers, wastewater equipment and industrial panels. Send the project dimensions, thickness, quantity, support layout and operating conditions before the sheet format is confirmed.
Large and thick formats are project-supplied products. This page does not state that every dimension is held in stock.
Large panels and thick sections must be reviewed with the component drawing, support arrangement, transport route and fabrication plan.
Extra-thick sheet requirements can be discussed for the project. The exact grade, tolerance, quantity and production availability must be confirmed.
Wide-sheet requests are subject to production, handling, packaging and order confirmation.
Provide the final panel schedule and repeat quantity so the production and packing plan can be reviewed as one scope.
Large sheets need an agreed handling, protection, lifting and storage plan from dispatch to fabrication.
For a large or extra-thick PP sheet project, submit the required panel dimensions, thicknesses, quantities and intended components before requesting a sample. State whether the sample is for color, surface, machining, welding or documentation review.
A small coupon cannot represent the span, support, welded joints, pressure, vacuum or complete performance of a fabricated tank or tower.
The following ranges prepare the project discussion. Final grade, dimensions, tolerance, order quantity and production availability are confirmed for the order.
| Standard thickness group | 3, 4, 5, 6, 8, 10, 12, 15, 20, 25 and 30 mm. |
|---|---|
| Extra-thick discussion group | 40 to 100 mm; subject to project confirmation. |
| Historical standard sizes | 1,220 × 2,440 mm and 1,500 × 3,000 mm. |
| Custom width and length review | Widths up to 3,300 mm can be discussed. Submit the exact length, width, thickness, quantity, cut plan and handling constraints. |
| Colors | Natural, beige gray, porcelain white and milky white are historical references. Confirm the current grade and color for the order. |
| Tolerance and availability | Confirmed with the named grade, dimensions, quantity and production plan. No full-range tolerance or stock commitment is stated on this page. |
Large panel performance depends on more than a coupon property. Sheet thickness, unsupported span, support spacing, temperature, load, pressure or vacuum, openings, welded joints and installation details must be reviewed together.
| Test item | Sample result | Method |
|---|---|---|
| Density | 912 kg/m³ | ASTM D792-20 |
| Flexural test result | 1,870 MPa | ASTM D790-25 |
| Tensile strength | 30 MPa | ASTM D638-22 |
| Elongation | 37% | ASTM D638-22 |
| Tensile modulus | 1,820 MPa | ASTM D638-22 |
| Izod notched impact strength | 59 J/m | ASTM D256-24 |
| Deflection temperature under load | 137.0°C | ASTM D648-18 |
| Vicat softening temperature | 155.2°C | ASTM D1525-25 |
Every value above belongs to a tested QEEHUA PP sheet sample. The production grade and conditioning are not stated in the source record. The values are not a universal grade specification, finished-part calculation or continuous service temperature.
QEEHUA does not provide a universal tank-wall thickness from this page. The responsible project team must assess geometry, supports, loads, pressure or vacuum, temperature, chemical duty, joints and the applicable design requirements.
Review the tank geometry, medium, concentration, temperature, liquid head, supports, nozzles, joints and inspection plan.
Provide tower diameter or panel dimensions, gas and condensate conditions, pressure or vacuum, supports, internals and fabrication sequence.
Review the water chemistry, basin layout, supports, covers, cleaning cycle, temperature and joining plan.
Use the cut plan and support drawing to define panel size, edge condition, identification and handling.
Confirm the enclosure dimensions, access openings, support frame, operating environment and surface requirements.
Use production and packing evidence to verify what is visible, then connect it to the order documents. A photograph supports identification and handling review. It does not prove tolerance, material grade or finished-equipment performance.
The photograph shows full panels. Confirm the ordered dimensions in the commercial and inspection records.
The photograph shows sheet packs supported flat before dispatch. Confirm the project handling plan separately.
Review edge protection, pack support and planned handling points for the actual shipment.
For extra-thick cross sections, request an image of the actual edge and thickness reference with the product or order identifier.
Send the panel schedule with width, length, thickness, quantity, color and drawing revision. Include cut labels, edge requirements, packing groups and the sequence needed by the fabricator.
A wider sheet may help reduce selected joints, but the result depends on the tank geometry, panel layout, production size, transport route and fabrication method. Treat seam reduction as a project objective, not a fixed percentage.
QEEHUA can review the sheet request and confirmed cutting scope. Structural design, lifting engineering, tank calculation and final fabrication approval remain with the responsible project parties.
