How to specify a cotton-canvas tarpaulin.

Control the finished cover, not just a nominal cloth weight. The edge construction, eyelets, treatment, seams, packing and acceptance plan change both performance and price.

Use case and size

Begin with the load, exposure and finished dimensions.

A machinery cover, groundsheet, agricultural cover and transport tarp fail in different ways. State what is covered, how the tarp is supported or tensioned, expected exposure, handling frequency and required service life.

Finished dimensionsSpecify finished length and width after hems, seams and treatment, with tolerances. State whether dimensions are measured laid flat and under what conditioning.
Panel layoutControl seam direction, number of panels, joins and whether seams may cross high-wear or water-shedding areas.
EnvironmentRecord rain, sun, dust, abrasion, temperature, storage, contact surfaces and whether condensation or breathability matters.
Canvas and treatment

Define what the cloth must be, not how it should feel.

State fibre composition, finished cloth mass, colour, treatment and acceptance tolerances. Water-resistant, waterproof, breathable and flame-retardant are not interchangeable. Each performance word needs a test or agreed acceptance method.

MaterialState cotton content or allowed blend, finished mass per square metre, weave or construction where needed, and substitution rules.
Performance treatmentDefine water, rot, mildew, flame, UV or other requirements separately and name the evidence or test required for each.
CompatibilityIdentify contact with painted surfaces, food, chemicals, heat or sensitive equipment and any prohibited treatment ingredients or transfer risks.
Edges, eyelets and stress points

Most field failures start outside the main cloth.

Specify hem construction, internal reinforcement, eyelet material and spacing, corner patches, handles, straps, ropes and any shaped cut-outs. A quoted eyelet spacing should state whether it is maximum spacing or nominal spacing.

PerimeterDefine fold count or finished hem, reinforcement material, thread, seam performance and treatment of cut edges.
EyeletsSpecify material, internal diameter where necessary, corrosion expectations, spacing, corner placement and pull-out acceptance.
Corners and load pointsControl patch size, layers, stitching, D-rings, webbing, loops or handles and the load direction they must resist.
RepairState whether patches, thread, adhesive, spare eyelets or a repair method must be included in each pack or shipment.
Inspection and quotation

Price the finished tarp and its delivery evidence.

The quotation should list cloth basis, treatment, finished size, reinforcement, eyelets, unit packing, shipment packing, source, sample timing, production timing and every exception. Require pre-production approval where colour, treatment or hardware is not already evidenced.

Pre-productionApprove a cloth swatch, treatment evidence, hardware sample and construction sample before bulk work where the risk warrants it.
Final inspectionCheck finished dimensions, visible defects, seams, reinforcement, eyelet count and placement, packing and lot identification against an agreed sampling plan.
Commercial basisState quantity by size, destination, Incoterm, delivery date, split-shipment rules, currency, validity, payment and inspection cost allocation.
What turns a canvas tarp description into a specification?

A finished-size tolerance, fibre and cloth basis, treatment fields, panel and seam rules, reinforced edges, eyelet or grommet details, load points, packing, sampling, inspection and order-specific evidence.

Order-specific evidence only.BNC does not claim a universal tarp weight, treatment, test result, source capacity or delivery time. The proposed construction is documented in the quotation.

Direct answers

Buyer questions, answered directly.

Should tarp dimensions be nominal or finished?

Use finished dimensions after hems, seams and treatment, with a tolerance and measurement condition.

Is eyelet spacing enough to specify an edge?

No. Also define eyelet or grommet material, internal diameter where needed, corners, hem and reinforcement construction, load direction and acceptance.

Does this guide cover PVC truck tarps?

No. It is written for cotton-canvas tarpaulins. Synthetic covers require a separate material and sourcing decision.
