Quality & installation standards

How SVARA Castings products are tested, certified, and correctly located on site.

Certification

Independently tested, not self-declared

Two standards sit behind every cover, frame and grate we cast — one for the quality system that makes each pour repeatable, one for the physical performance of the finished product.

01 Quality management

ISO 9001:2008

Our products have been independently tested under a quality system in accordance with ISO 9001:2008 — covering everything from incoming raw material to the finished, inspected casting.

02 Product performance

BS EN 124:1994

Assessed and certified as meeting the requirements of EN 124:1994, with recognition under the British Standards Institution (BSI) Kitemark® scheme, covering load class, dimensions and material performance.

From pattern to pour

How a SVARA casting is made

Ductile Cast Iron takes its strength from a controlled, repeatable process — every stage checked before the next begins.

01 01

Pattern & mould preparation

Sand moulds are prepared to the exact internal and external dimensions specified for each product code — from a 150×150mm dish grate to an 1100×1100mm manhole cover.

02 02

Melting & metallurgy

Ductile iron is melted and its metallurgical composition checked before pouring, so the finished casting delivers the corrosion resistance and structural strength the standard requires.

03 03

Casting & cooling

Molten iron is poured into the prepared mould and allowed to cool under controlled conditions, giving ductile iron its characteristic machinability and resistance to ground movement.

04 04

Finishing & fitment

Covers are fitted to their frames, hinges and locks tested, and hardware — rubber seals, bolts, lifting keys — matched to the product type.

05 05

Inspection & load testing

Each product line is checked against its rated class — B125, C250 or D400 — before it is released against a customer order.

Installation guidance

Where a cover is installed matters

Every product in our catalogue is rated for a specific installation area, from footways through to full carriageways. Choosing the correct class for the site is central to the product's long-term performance.

B125 12.5 TON

Footways & pedestrian areas

Parking areas for cars, bicycle ways, and pedestrian ways.

C250 25 TON

Kerbside channels of roads

Kerbside parking areas subject to occasional vehicle loading.

D400 40 TON

Carriageway of roads

Roadways and parking areas for all types of road vehicles.

Liability

Installation locations referenced in our documentation are stated in accordance with the provisions of standard EN 124:1994 (Kitemark Certification). Under no circumstances can SVARA Castings be deemed liable for having recommended an installation location on the basis of this documentation. Final responsibility for correct class selection and installation rests with the appointed engineer or contractor for each site.
