Overview

• The real comparison between tarpaulin quotations rests on three numbers, not on adjectives. The first number is the weight in grams per square metre, the only indicator directly comparable between one quotation and another, because it describes how much material there is in the same area; this tarpaulin is 150 GSM. The second number is the eyelet spacing: a tarpaulin usually fails not in its middle but at its eyelets, because wind pulls on it and concentrates the whole force on a small number of tie points until one of them tears and the rest follow — and this tarpaulin carries an eyelet every single metre around the perimeter, so the load is spread across more points and the sheet flaps less in the wind. The third number is the actual size, which deserves particular attention on this item because its sizes are declared in yards while the local market works in metres — so the size table carries the metre equivalent for every size, allowing the required area to be matched before the purchase rather than after it. The construction is two layers, each with its own job: woven HDPE fabric gives the body and the tensile strength, and the LDPE lamination closes the pores between the woven threads, which is what makes it 100% waterproof; it is also UV treated. It is double faced — orange on one side and blue on the other — so the exposed face is chosen to suit the site. It is available in nine sizes from 6 by 4 yards up to 20 by 20 yards, plus a 2 by 50 metre roll cut to need on site, and the country of manufacture is India. Available from Al-Najma Al-Wataniyah Est. with a quality guarantee and fast supply to projects across the Kingdom in Riyadh, Dammam and all regions.

Technical Specifications

Size & Color Table

• The colour is orange and blue in every size. The metre equivalents are calculated by conversion (1 yard = 0.9144 m) and rounded to the nearest tenth of a metre:

Documentation & Standards

• In practice a tarpaulin is read from four elements: the structure of its two layers, its weight in grams, its treatment against the sun and the spacing of its tie eyelets. Below is what each element of this item's specification means in practice for the buyer:

• Additional reference standards for the Saudi market:
• ISO 2286 (determination of mass per unit area in coated fabrics — the basis of the grams-per-square-metre figure)
• EN ISO 1421 (determination of tensile strength and elongation in coated fabrics)
• EN 13501-1 (fire classification of construction products and building elements)
• NFPA 701 (test for flame propagation in textiles and hanging covers)
• For work whose specification calls for a fire performance classification (such as EN 13501-1 or NFPA 701) or for a higher weight per square metre, our technical team will recommend the item that carries the required specification together with its certificate and attach it to the project file.

Frequently Asked Questions

Q1: How do I compare tarpaulin quotations?

• By the weight in grams per square metre. It is the only figure directly comparable between one quotation and another, because it describes how much material there is in the same area. This tarpaulin is 150 GSM. The practical rule when requesting quotations: ask for the weight in grams with every offer, because comparing price alone between two different weights is not a valid comparison in the first place.

Q2: Why does eyelet spacing of one metre matter so much?

• Because a tarpaulin does not fail in its middle but at its eyelets. When wind pulls on it, the whole force concentrates on the tie points; if those are few, each eyelet carries a greater load until one tears, and its load then transfers to its neighbours, which follow one after another. An eyelet every metre means more tie points, a wider spread of the load and less flapping — and repeated flapping is itself a fatigue factor that wears the tarpaulin out over time.

Q3: What is the difference between the HDPE and LDPE layers?

• Each layer has a different job. The woven HDPE is the load-bearing layer: interlaced threads that give the tarpaulin its body and its resistance to tension at the tie points. The LDPE lamination is a layer that closes the pores between the threads — a weave on its own, however strong, still has gaps between one thread and the next that water passes through, and the lamination is what turns it into a 100% water barrier. The first gives strength; the second gives the seal.

Q4: What is the benefit of a double-faced tarpaulin in two colours?

• That the tarpaulin is finished on both sides, so there is no outer face and an unfinished inner one, and it can be used on either face. The practical benefit is in the choice: the orange face is more visible from a distance, which suits sites where what is covered should be marked or stand out, while the blue face is visually quieter for anything that should not draw attention. The decision is left to the site, and the tarpaulin is the same either way.

Q5: Do you deliver to Riyadh, Dammam and all regions of the Kingdom?

• Yes — supply is available to every region of the Kingdom, Riyadh, Dammam, Jeddah, Jubail, Yanbu and all other regions, within 2-3 Business Days. For large quantities the B2B team matches the required area against the available sizes in metres, recommends the roll instead of ready-made sizes where cutting on site is more economical.
