T1130 Corrugated UPVC Roofing Sheet | HESU

T1130 corrugated UPVC roofing sheet is HESU’s solid profiled sheet with a listed effective coverage width of 1130 mm. Current thickness options run from 1.5 mm to 3 mm. The repeating corrugations form drainage channels and add profile stiffness. The installed result still depends on the approved drawing, roof slope, support layout, laps, fasteners and thermal movement.

T1130 belongs within the broader UPVC roofing sheet family, but it has a distinct solid corrugated structure. It is not the T940 double-layer hollow panel, and it is not a Spanish-style resin tile. That distinction keeps the material description, drawing and installation details tied to the correct product.

T1130 Corrugated UPVC Roofing Sheet Specifications

The table separates currently listed HESU values from project-dependent items. A current production drawing and written specification control the final order.

The 1130 mm value describes effective installed coverage, not an assumed sale width. Effective coverage is the roof width left after the designed side lap. Order calculations that use an unverified total width can understate sheet quantity and shift the final sheet away from the intended roof edge.

How Does the T1130 Corrugated Profile Work?

A corrugated profile alternates raised crests and drainage valleys across the sheet. This shape gives a thin sheet more working stiffness than a flat sheet of the same material. It also creates repeated channels that carry water toward the eave.

The profile works only when adjacent sheets nest correctly. The side lap must follow the approved edge geometry, and the first sheet must remain square to the eave. A forced lap can store stress in the sheet. It can also open another part of the joint or distort the drainage line.

Support positions and screw lines must match the same profile drawing. A fixing that lands away from stable support can pull the corrugation out of shape. Excess washer pressure can lock the sheet or crush the profile locally. Low pressure can leave a water path and allow movement under wind.

Roof area calculations should use effective coverage, slope length, side laps, end laps, edge conditions and a justified allowance for cuts. HESU’s guide to calculating roofing sheet quantity explains how these variables connect.

What Does the UPVC Body Contribute?

UPVC means unplasticized polyvinyl chloride. The rigid formulation helps a formed sheet retain its corrugated shape. Final behavior still changes with formulation, thickness, profile depth, temperature, production control and support conditions. The material name alone does not establish load capacity or service life.

The plastic sheet body does not rust in the same way as exposed steel. This makes T1130 relevant where humidity, salt, livestock moisture or selected industrial atmospheres make unprotected metal difficult to maintain. The complete roof still contains vulnerable interfaces. Screws, washers, purlins, flashings and standing water all affect corrosion performance.

Chemical resistance also requires a defined exposure. Concentration, temperature, contact time and cleaning practice can change the result. HESU reviews the roof as a system, as shown in its technical discussion of UPVC roofing sheets in coastal areas.

Where T1130 Fits in the HESU UPVC Range

T1130 is the solid corrugated option in HESU’s UPVC range. Its geometry supports practical water shedding across workshops, warehouses, agricultural buildings, storage roofs and selected renovation structures. Each project still needs a suitable roof slope, frame condition and local structural review.

• Industrial workshops: corrugated channels create a direct drainage pattern, while the non-metallic body avoids sheet-body rust.
• Warehouses and storage buildings: the lightweight formed sheet can simplify handling when lifting plans and support conditions suit the selected length.
• Agricultural roofs: UPVC can separate the roof covering from corrosion that affects exposed metal, but ventilation, condensation and fastener selection remain essential.
• Coastal buildings: the sheet body resists metallic corrosion, while the fastening and support system still needs exposure-appropriate materials.
• Renovation roofs: T1130 may reduce added covering weight, but the existing frame must be straight, stable and suitable for the new fixing layout.

T1130 is less suitable when a project requires transparent daylighting, a decorative Spanish tile profile, a verified non-fragile assembly, a documented fire classification or structural values that the selected sheet cannot demonstrate. Those requirements need another HESU system or project-specific evidence.

How HESU Controls the Corrugated Profile

Profile consistency begins during extrusion and forming. The sheet needs controlled thickness, a repeatable corrugation, stable cooling and clean edges. Variation in any one of these areas can affect how two sheets nest at the side lap.

HESU checks the formed profile as a production component rather than judging only the visible surface. Relevant controls include thickness across the sheet, crest and valley shape, edge condition, color consistency and the fit between adjacent samples. The approved sample must connect to the written profile and thickness on the order.

The HESU roofing sheet factory also controls handling after forming. Corrugated sheets need even stacking and support. Concentrated strap pressure, rough lifting or an uneven bundle can deform edges before the material reaches the roof.

Installation Conditions That Control T1130 Performance

The current T1130 drawing must guide roof setting-out. It should define the total and effective widths, side-lap direction, permitted end-lap arrangement, fixing positions and compatible accessories. Project design must then establish roof slope, purlin spacing, wind actions, edge zones and drainage length.

UPVC expands and contracts as roof temperature changes. Long sheets accumulate more movement than short pieces. Hole preparation, washer selection, screw alignment and tightening pressure must allow the selected system to move without losing its seal. T1130’s rigidity does not remove this requirement.

Installation should begin with a straight eave reference and a square first sheet. Every later panel follows that alignment. Side laps should nest without force, and fasteners should enter the support at the designated position and angle. Ridge, verge, wall and penetration details must release water onto the corrugated surface instead of trapping it behind a trim.

A corrugated plastic roofing sheet must not be treated as a walking surface. Roof installation, inspection and maintenance require competent planning, fall protection and local safety compliance. Product impact resistance does not prove that an installed roof assembly can support a person.

Packing and Delivery of Long Corrugated Sheets

Long T1130 sheets need level support through packing, loading, transport and site storage. Bundles should keep edges aligned and distribute restraint without crushing corrugations. Product labels should identify the profile, thickness, color, length and batch so site teams can separate similar-looking materials.

The delivery plan also needs realistic lifting space. Dragging a long sheet across another panel can mark the surface or damage an edge. An uneven storage base can introduce twist, which later appears as poor lap nesting. HESU confirms bundle arrangement and loading details against the selected length and shipment plan.

T1130 Corrugated UPVC Roofing Sheet FAQ

What does T1130 mean?

T1130 is HESU’s designation for a solid corrugated UPVC roofing profile with a listed effective coverage width of 1130 mm. The current HESU drawing defines the complete geometry.

Is 1130 mm the total sheet width?

HESU currently lists 1130 mm as the effective coverage width. Do not treat it as total width without checking the current drawing. Effective width is the installed coverage left after the designed side lap.

Which T1130 thicknesses are available?

The currently listed range is 1.5 mm to 3 mm. Final availability, weight and production details depend on the selected construction and written specification.

Does T1130 rust?

The UPVC sheet body does not rust like exposed steel. Metal fasteners, supports and flashings can still corrode, so material compatibility and drainage remain part of the roof design.

What purlin spacing does T1130 require?

No universal spacing should be copied from another profile. The project must use the current T1130 guidance together with sheet thickness, roof load, slope, wind exposure and structural design.

Can installers walk directly on T1130 sheets?

No walkability claim is made for the sheet or roof assembly. Roof work requires a competent safety plan and suitable access and fall-protection equipment. Treat the roof as fragile unless verified assembly evidence states otherwise.

What information does HESU need for a T1130 specification?

Provide the building use, roof layout, slope, support arrangement, required sheet length, thickness, color, quantity, accessories and destination. HESU can then return the current profile drawing, confirm production options and prepare a project-specific quotation.
