900gsm PVC Coated Truck Side Curtain Fabric

1. 900gsm PVC Coated Truck Side Curtain Fabric: Category Overview

(1) What the Fabric Is

900gsm PVC Coated Truck Side Curtain Fabric is a coated textile made for the movable sidewalls of curtain-sider trailers. A polyester scrim carries the tension, PVC coatings on both faces seal it against rain and spray, and a surface lacquer keeps the outer face smooth for cleaning and printing. The figure 900gsm refers to the finished weight of the fabric in grams per square meter, counting scrim, coatings and lacquer together.

(2) Why the Weight Class Matters

Weight is a simple way to describe how much material sits in each square meter of curtain. A heavier class carries more scrim and more coating, which adds margin for wind pressure, load contact and repeated opening. A lighter class is easier to slide and fold. A 900gsm build sits on the heavy duty side of that choice, so it is usually discussed for long haul trailers, exposed routes and loads that press against the curtain.

This guide explains how the fabric is built, how it works on a trailer, what its weight means in practice, and how buyers can brief a factory.

2. Structure and Working Principle

(1) How the Weight Is Built Up

The waterfall chart shows how the layers of a 900gsm build can add up to the finished weight. The scrim comes first and gives the fabric its tensile backbone. The outer coating adds the next block, which seals the surface and gives the sheet its water resistance. The inner coating adds a similar block on the back side, so the cloth stays balanced and lies flat when welded. A thin lacquer layer finishes the outer face and adds little weight. The final bar shows the combined 900gsm total. The split is an example only, since scrim yarn, coating thickness and lacquer system change from one design to another, and the factory should confirm the real build for each order.

(2) Coating and Lamination Routes

Knife coating spreads PVC paste on the scrim with a blade and gels it in an oven. Hot lamination fuses pre-made PVC film to the scrim under heat and pressure. Cold lamination bonds film and scrim with an adhesive system at lower temperature. Each route changes surface feel, thickness control and flexibility, so a factory matches the method to the curtain design and the climate of the route.

(3) Welding and Edge Work

PVC is a thermoplastic, so curtain panels are joined by high frequency or hot air welding, which fuses the coating of overlapping edges into one layer. Welded hems and pockets then carry roller carriages, straps and lashing hardware along the edges of the curtain.

3. The Curtain as Part of the Trailer

A side curtain works together with rails, rollers, posts and straps. The schematic below shows the main parts of a curtain-sider side wall.

The curtain hangs from roller carriages on the top rail and is held at the base by straps and buckles. Corner posts mark the ends of each section and take the load of the curtain when the trailer is closed. The printed face of the curtain turns the trailer side into a fleet display, which is why a smooth lacquer surface matters. In wind, the curtain behaves like a large sail, and the fabric passes that load to the straps, posts and rail through welded hems. A 900gsm build gives the panel more material at those hems and edges, where the force concentrates. The curtain still has to slide freely, so weight, flexibility and hardware must be matched to each other.

4. What 900gsm Means in Practice

Fabric weight can be turned into a concrete figure for one trailer. The number line below uses an example curtain 13.6 m long and 2.7 m high, which is about 36.7 square meters on one side, and shows the fabric weight at three classes.

The markers show fabric weight for one side of the example trailer at three weight classes. A 600gsm curtain weighs about 22 kg, a 750gsm curtain about 27.5 kg and a 900gsm curtain about 33 kg for the same area. The gap between the lightest and heaviest class is about 11 kg per side, or about 22 kg across both sides. That is a modest share of a loaded trailer, but it matters for the effort needed to slide the curtain by hand. In return, the heavier class adds scrim and coating, which raises tear margin and gives hems and edges more material to hold hardware. The figures are a simple area times weight calculation, and real curtains also carry hems, straps and reinforcement.

5. Common Types and Application Cases

(1) Common Types

(2) Application Cases

• Long haul logistics: curtain-sider trailers that spend long hours at highway speed and meet crosswinds.
• Palletized and bagged cargo: loads that press on the curtain and test hems and straps.
• Construction and building materials: side loaded flatbed and curtain trailers with frequent handling.
• Fleet branding: printed curtains that carry company names and route marks.
• Trailer builders and retrofit shops: OEM programs that need matched rolls and repeatable weight.

6. Selection Points

Choosing a weight class is a short decision path. The tree below shows a simple way to reach a first answer before talking to a factory.

The decision tree starts with the route, because route length and wind exposure drive the loads on the curtain. A yes at the first question leads to the 900gsm class, where the extra material gives more margin against wind pressure and load contact. A no leads to a second question about handling, since short routes with many stops reward lighter curtains that slide easily. A yes at that point points to the lightweight class, while a no points to the medium class. Real projects have more variables, such as trailer length, load type and driver handling, so the tree is only a starting point. A factory can refine the answer once it sees the trailer drawing and the working conditions.

1. State trailer type, curtain length and height, and the number of sections.
2. Describe routes, wind exposure and how often the curtain is opened.
3. Confirm the weight class, with 900gsm for long haul and exposed use.
4. Select color, lacquer finish and the print area for fleet graphics.
5. Agree on roll width, hem and pocket details and the welding method.
6. Request samples and run sliding and welding tests on a real trailer section.

7. Factory Capability Behind the Fabric

A heavy curtain fabric needs steady coating and consistent roll weight from the first roll to the last. Anhui Kingtex Material Technology Co., Ltd. works as a China PVC fabric waterproof manufacturer and stretch PVC fabric factory. Its range covers architectural membranes, PVC tarpaulins, PVC inflatable fabrics, mesh fabrics, biogas membranes, knife-coated fabrics, disaster prevention nets and intelligent luminescent materials.

The company operates PVC cold lamination, hot lamination and coating equipment, together with a full set of testing instruments and a dedicated R&D team. For buyers looking for a 900gsm PVC Coated Truck Side Curtain Fabric Factory or a PVC truck side curtain fabric manufacturer, this means weight class, coating build and testing can be reviewed together, including OEM, custom color and roll width requests. Customers from all sectors are welcome to visit the facility for tours and business talks.

8. Maintenance Guidance

A heavy curtain stays in good condition when it is cleaned and checked on a regular schedule.

1. Wash with clean water, mild detergent and a soft brush, then rinse fully.
2. Avoid strong solvents and hard scrapers, which can mark the lacquer and printed graphics.
3. Check hems, pockets, straps and roller carriages for wear at regular intervals.
4. Keep rails and rollers clean and free running, so the curtain does not drag.
5. Pad sharp cargo edges and avoid loading against the curtain when possible.
6. Repair small cuts early with a compatible PVC patch applied by heat welding.
