6x20m Classic DIY Marquee

6m x 20m Marquee for Sale – Classic Heavy-Duty DIY Marquee

Our 6x20m marquee for sale is part of the Classic range, offering durability and style for events, weddings, and parties. Ideal for private users or anyone who wants a reliable and high-quality Flame Retardant PVC Marquee. PVC is widely regarded as having at least twice the lifespan of PE material and is superior to poly/PVC. It can also be joined using high-frequency welding (rather than stitching) to make a completely waterproof and reliable shelter.

An excellent 3-season marquee (additional precautions should be taken in unseasonal weather), ideal for occasional use in the domestic market. We recommend ground bar kits for added stability and tie-down kits unless you have your own method for anchoring the marquee down. As with all DIY marquees, should the unforeseen happen, any replacement part is available to purchase separately, and our experienced customer service staff are always available for any advice you may require.

6m x 20m Classic PVC 1600 Marquees feature:

  • 6x20m 500gsm Rip-stop PVC 1600 Roof cover
  • 6x20m 380gsm Rip-stop PVC 1600 Side Panels
  • Flame retardant to BS5438 & BS7837 for safety
  • High frequency welded PVC joins for complete waterproofing
  • Strong up to 42mm galvanised steel framework
  • 'Simplex' design (only 2 different length poles used throughout the marquee) for ease of erection
  • Vertical and Horizontal roof braces
  • Ground bars available for added strength (recommended)
  • 6m wide wall panels with zipped entrances at either end
  • Individual 2m window panels on both sides
  • Wind-stop velcro sealed joins for all side panels
  • 12-month warranty and full spares back-up service for peace of mind
  • Can be extended for future expansion

Premium Marquee Materials

Over the many years of manufacturing and supplying marquees we have used a wide variety of different PVC materials.

Over this time we have come to the conclusion that while other cheaper alternatives are available and can be described as the same weight there really is no substitute for quality and now exclusively use Duracoretex™ PVC in all of our PVC DIY Marquees.

More recently PVC has been described using a number, for example PVC 700, PVC 1400 etc. This denotes tearing strength. All of our PVC is 1666N. The strength of PVC comes from the tightly woven rip-stop core.

Additional Marquee Accessories

Groundbars: Groundbars are poles that connect the footplates to effectively make the marquee into a strong box. They give added strength to the framework and add to the stability of the Classic DIY Marquee (Tie downs or other means of anchoring to the ground are still required).
Eave braces: Eave braces give the roof frame added strength where it's most needed. They prevent the roof cover from stretching and therefore provide greater resistance to water pooling, extending the marquee's lifespan.
Roof lining: Transforms the interior by hiding the metalwork in the roof.
Roof and curtain/wall linings: Wall linings cover the PVC walls, while curtain linings add a finishing touch by hiding the metal legs. (Linings can be used as either walls OR curtains.)
Roof, wall, curtain, and swag linings: Swags add a gathered finish around the pelmet of the roof lining (includes walls and curtains).
Carpet flooring: Provides a smooth, trip-free surface (suitable for high heels). Includes waterproof underlay and nails. Carpet is supplied on a 2m wide roll.
Tie down kit: Strongly recommended for anchoring the marquee on soft surfaces. Consists of 6 large metal stakes and 6 ratchet straps (available in white or orange).
Over strap kit: Recommended for anchoring the marquee during winter in exposed areas. Consists of four 1m long metal stakes and two 2" wide x 15m long ratchet straps.
White marquee festoons: A string of 10 x LED bulbs that can fit above the roof lining.
Retro marquee festoons: A string of hanging retro-style bulbs with a long filament.
Carry bags and boxes: Ideal for storing and transporting your marquee. The marquee arrives in sturdy cardboard boxes.
Arcotherm indirect diesel heater: With ducting adaptor, ducting, rain cowl, and thermostat. Clean hot air is drawn into the heater from the rear by the internal fan. It is heated as it passes over a heat exchanger. The combustion by-products remain within the heat exchanger and are exhausted via the flue. Controlled by a thermostat within the marquee.

About DIY Marquees

DIY Marquees is an independent family run company dedicated to designing, manufacturing and supplying quality marquees and accessories.

Having built up and successfully run one of the leading marquee hire companies in the UK, we now use that experience in advising other hire companies and designing and supplying commercial quality marquees, linings and accessories.

DIY Marquees:

DIY Marquees was formed by Spencer King having spent over 10 years in the marquee hire industry (due to the sale of the hire company we are contractually not allowed to hire any of our marquees). It has been set up to provide marquee hire companies with high quality marquees and linings whilst also offering advice and industry contacts from experience.

C & D King Ltd:

C & D King Ltd has been manufacturing in the UK since 1979.

Originally set up by Colin & Diana King they have now been joined in the family business by their son Spencer who has added marquee experience to the engineering background of Colin.

We recently calculated the average length our employees have worked for us at over 18 years! That's longer than most others in the industry have been in business.
