ERMATIC® ACCESS COVERS AND FRAMES FEATURES 

Ermatic® is a comprehensive and highly specified range of access covers for diverse underground services 

Sewerage: inspection pits for sludge chambers, access shafts for large plants. 

Telecommunications: cable jointing chambers. 

Electricity: lighting, signals, transformer pits, cable joint boxes. 

Potable water, gas, district heating, valve chambers, manifold chambers and meter chambers 

In the following environments: 

Airports and ports, 

Railways, 

Power stations, 

Water treatment and purification plants, 

Manufacturing plants, 

Industries, 

Exhibition centres, leisure parks, tunnels, Stadiums... 

Ermatic® assures protection against damage, debris or aggressive chemicals, and allows designers to 

conceal underground services, maximising productive use of the unobstructed surface. 

Modular construction 

The use of modular elements gives a vast range of sizes 

rame elements (side frames and end plates) are assembled using bolts and aluminium joints to provide 

linear openings for even the longest ducts. 

Above clear opening spans of 1200 mm, Ermatic® units employ removable beams supported in boxes 

which are fixed to the frames. This permits the construction of units to suit the largest openings. 

1/2/3 – part unit 

Duct cover 

Multiple unit with 

removable beams 

Stability and sealing 

The horizontal and vertical faces of the cover and frame are machined to give metal-to-metal contact between the seating faces, within a tolerance 

of 0.2 mm. 

Stability: when correctly installed, Ermatic® products are non-rocking, silent under traffic and prevent the ingress of dust and debris. 

Sealing: the addition of a film of grease to the machined contact faces of the cover and frame renders the Ermatic® cover watertight 

under normal rainwater conditions.

ES 

Environment, security, ergonomics, the Ermatic® range benefits from the advanced technology of the 

Norinco Group: 

aesthetics of the project is enhanced: the covers can be recessed to receive a similar material to the 

surround, 

rapid and easy access for maintenance and development of the network, 

security reinforced by the strength and stability of the covers. 

GENERAL PRESENTATION 

Types of surface finish available 

Designed for a wide range of applications, The Ermatic® range offers a choice of covers 

to suit every specification of performance and/or appearance. 

Solid top cover with uniform anti-slip surface 

This cover offers unequaled performance whilst being lighter than recessed covers of a comparable size 

when filled with concrete. Installation costs are reduced and the performance is not influenced by the quality 

of the concrete infill. 

Cover recessed for concrete infill 

In classes B 125 and C 250, the ribs are positioned below the surface of the cover to permit the installation of thin 

paving.This type of cover is particularly suited to large openings where aesthetic considerations are a priority. 

The concrete infill is undertaken in accordance with the requirements of EN124 and with Norinco’s 

specifications detailed in this brochure (see page 85) 

Other types: 

Covers recessed for small element paving for pedestrian areas (see pages 20 - 42 - 64) 

Cover with central removable plug (see pages 22 and 34) 

Painting 

Covers and frames: painted with water soluble black paint except for machined surfaces and surfaces 

in contact with concrete. Where products are delivered in a dismantled condition, all machined 

surfaces are coated with a protective film. 

Handling with ease 

Covers slide in and out of the frame along greased, machined seatings, requiring no vertical lift. 

Ermatic® key: ergonomically assists with safety. Further reduces the effort required to remove and replace 

covers. 

Universal keyways 

For use with many different types of common lifting keys. 

Fitted with polyethylene blanking plugs to prevent the entry of debris or concrete. 

Ribs extend below the underside of the cover 

To protect the machined seatings, the reinforcing webs are deeper than the cover. This also prevents 

any greased surfaces coming into contact with the floor (except for some B 125 recessed covers). (see 

handling page 86) 

Locking of the covers 

In order to ensure an easier and more optimised installation of our Ermatic® systems, it has been 

decided to supply all the products in D400 systematically locked. For E600 and F900 productslocking 

is recommended for the same reasons. 

Adjusting bolts 

In order to facilitate the levelling of Ermatic® systems, adjusting bolts are supplied with 

the products. These bolts will allow, if necessary, to adjust the height of the system to the 

final level and correct any possible defects of the civil work.

Products are made from 100% ductile iron: 

Ductile iron provides reliability and strength. Ductile iron 

is produced by converting the inherently brittle grey cast 

iron, by the addition of magnesium before pouring. This 

gives a material with high flexibility, particularly resistant to 

forces and shock. (See p. 87) 

ISO 14001 

Environmental responsibility, conformity 

with standards, compliance with laws 

and a resolutely eco-friendly approach 

are all factors strengthening NORINCO’s 

reputation, its image and its growth 

potential. Protecting the environment 

is at the heart of our strategy. 

NORFOND is ISO 14001 certified since 

2008.

COVER AND FRAME CONFORMITY 

EN124 Standard 

Ermatic® Range 


Determines the following characteristics of covers and frames: 

Principles of construction: frame depth, depth of insertion, seatings, 

surface condition etc. 

Material used for the manufacture of covers. 

Testing regime: test loads and permanent set limits 

All Ermatic® covers are designed to meet all the 

requirements of the EN124 standard. 

All Ermatic® covers are manufactured from ductile iron according 

to ISO 1083 and EN 1563. 

All solid top covers and recessed B125/C250/D400/E600 

covers are tested in the as-cast condition and meet all the test criteria 

of the EN124 standard. F900 recessed covers and 

ER6R ...120 attain resistance characteristics after filling with 

concrete, complying with EN124 standards and the recommendations 

on page 85. 

Loading and conformity certificates in accordance with the requirements 

of EN124 

The dimensions of removable beams in multiple units are 

derived from the following French 

specifications 

Ermatic® B 125: .....................Loading 500 daN/m 2 

Ermatic® C 250: ..............CCTG volume 61 - clause 2 

Ermatic® D 400: ..............CCTG volume 61 - clause 2 

Ermatic® E 600/F 900: ....................ADP and STBA 

Requires a quality system equivalent to ISO 9002. 

Requires that products are clearly marked with the mark 

of a certification body. 

The design and manufacture of Ermatic® covers is undertaken 

within one facility operating a quality system certified by third party 

to ISO 9001. 

The EN124 standard is limited to covers with a clear 

opening dimension 1000 mm. Consequently, units above this 

dimension, particularly those that utilise removable beams, are 

outside the scope of EN124. However, some 1,2 and 3 part solid 

top units, from which multiples are constructed, carry third party 

certification to conform with the requirements of EN124 (please 

consult us for further information). 

Product characteristics are dependent upon correct installation in accordance with the recommendations on p. 79. 

Drawings, photos, dimensions and weights are given as an indication without any contractual value. Our policy is one of 

continuous product improvement, we reserve the right to modify product specifications without prior notice.
