Window Screen Fabric

Window screen fabric is the roll-form base material used to make window screens. It is a fiberglass plain-woven mesh with PVC coating, standard 18 × 16 mesh per square inch, weight 110–120 g/m², yarn diameter 0.23–0.25 mm. It is supplied as uncut rolls for buyers who cut, frame, or repack the material themselves.

For B2B buyers, the buying decision here is about material sourcing rather than finished product selection. The points that affect cost and downstream yield are roll width, roll length, batch weight consistency, and coating behavior during cutting and framing.

• Check roll weight against the stated g/m². Weigh one roll, measure its area, and calculate g/m². Compare against the order specification.

• Check mesh count on three points of the roll. Count mesh per inch at the left edge, center, and right edge. Deviation should be within ± 0.5 mesh per inch.

• Check coating adhesion. Fold a sample section and unfold it. The coating should not crack or separate from the base yarn at the fold line.

• Check roll edge condition. The roll edge should be flat and tightly wound. Loose winding or wavy edges cause feeding problems on automated cutting lines.

• Check for base yarn type confirmation. Buyers sourcing for outdoor use should confirm alkali-free fiberglass base yarn, as it affects long-term performance under moisture and UV exposure.

• Batch weight deviation ≤ ± 2 g/m². Within the same batch, roll-to-roll weight variation affects yield and quotation for buyers who resell by weight or run automated cutting lines.

• Batch code on each roll. Each roll carries a batch code. Buyers can trace the production batch for quality records and after-sales reference.

• Coating-to-substrate adhesion tested by peel test. The coating is applied by dip coating and tested to the referenced industry standard. This affects flexibility at fold lines and cut edges.

• Mesh deviation ≤ ± 0.5 mesh per inch. Warp and weft tension is computer-controlled. Uniform mesh supports consistent visual quality in framed finished screens.

• Cutting loss. Roll width should match your most frequent cut length. Wider rolls reduce offcut when cutting multiple sizes. Narrower rolls reduce offcut for single-size cutting.

• Framing loss. Cut edge resists fraying, so no heat cutting or edge binding step is needed. This reduces one processing step and the associated material loss.

• Folding and packing loss. The mesh can be folded for packing without edge binding. Fold lines do not crack or separate, so no material is lost to folding damage.

• Roll change loss. Longer rolls (50 m, 100 m) reduce the number of roll changes on the cutting line. This reduces downtime and material loss at roll changes.
