These best practice design manuals consist of a series of technical guides for engineering offices, steel fabricators, and architects that aim at facilitating the application of the Eurocodes in the design of single-storey and multi-storey steel buildings.

The presented design manuals consist of a series of technical guides facilitating the application of the Eurocodes in the design of single-storey and multi-storey steel buildings.

These design manuals are helpful for steel fabricators and engineering offices, but the presentation of the advantages and possibilities of the use of steel also applies to architects. They provide a useful source of knowledge for designers in accordance with the Eurocodes and include topics such as numerous design details, fire engineering issues, member and connection resistance calculators, etc.

The design guides 'Single-Storey Steel Buildings' and 'Multi-Storey Steel Buildings' were produced in the framework of the European project 'Facilitating the market development for sections in industrial halls and low rise buildings (SECHALO) RFS2-CT-2008-0030', which was carried out with a financial grant from the European Union's Research Fund for Coal and Steel.

The design guides were prepared under the direction of ArcelorMittal, Peiner Träger, and Corus. The technical content was prepared by CTICM and SCI, collaborating as the Steel Alliance.

Galeria Północna, a modern and functional new shopping centre has recently opened its doors in Warsaw (Poland). It was built using 6,000 tonnes of rebars produced by ArcelorMittal Europe – Long Products.

The shopping centre includes in total 250 stores located on 3 floors as well as a cinema multiplex with 11 rooms and several restaurants for a total of 64,000 m² of leasable space. The project involves the active use of the roof, where a garden with an open children playground will be built. An underground parking was also constructed, offering 2,000 parking spaces.

ArcelorMittal Warszawa was the main steel supplier and provided 6,000 tonnes of rebars which were used to reinforce the foundations of the centre and of the underground car park.

Galeria Północna will contribute to the attraction of the Białołęka district, in the North East of the capital city. Targeting mainly young people and families with children, it will not only attract customers living in the area, but also from other districts of Warsaw and its surrounding.

The intimate combination of steel and enamel has delighted artists for millennia. With enamelling steels architects and designers also have their chance to create enduring colourful designs for contemporary architectural projects. ArcelorMittal has now developed HC300EK, a new steel grade which is specifically adapted for enamelled architectural projects.

Architecture with enamelled steels - why?

The combination of 100% recyclable steel and enamel (made from glass and pigments) can fulfil both the aesthetic and sustainability aspirations of modern architecture. Furthermore, steel provides mechanical strength and formability, while enamel adds durability and a unique glossy finish.

ArcelorMittal’s enamelled steel grades are already adapted to the various processes used in enamelling. For example, one or more layers of enamel can be fired at high temperature (between 780 and 850°C) on the steel substrate.

HC300EK – the new enamelling steel grade

HC300EK is specifically adapted for enamelled architectural projects and offers:

• Perfect flatness of the facade envelope thanks to its guaranteed minimum yield strength after enamel firing
• Cost savings of up to 30% due to the reduced thickness of the steel substrate (for example, existing 1.5 mm panels can be produced in 1 mm). The mechanical properties of the steel remain the same after 5% deformation and enamel firing
• Easy handling of the panels and cassettes on site thanks to the lower weight

HC300EK is available in the following dimensions:

• standard thicknesses range from 0.5 to 2 mm. Thinner panels (to 0.32 mm) can be produced in consultation with ArcelorMittal
• standard widths range from 1,250 to 1,500 mm

Solfer® range meets all architectural requirements

ArcelorMittal’s Solfer® steels are the best solution for enamelled architectural projects. Solfer® grades provide:

• Perfect flatness of the facade envelope thanks to its limited deformation, even after multiple enamel firings
• A surface free of any defects after enamel firing

Solfer® grades are available in the following dimensions:

• Standard thicknesses range from 0.5 to 2 mm
• Standard widths range from 1,250 to 1,500 mm

Enamelled steels and their unique properties

• A wide array of colours and finishes
• Excellent resistance to abrasion and scratching
• Outstanding resistance to corrosion and ultraviolet (UV) light
• Resistance to the effects of atmospheric pollution

No other material on the market today can match the quality of ArcelorMittal’s enamelling steels for both indoor and outdoor applications.

Colours & Finishes

Enamelled steels are available in an almost infinite range of long-lasting colours, patterns and textures with a gloss, semi-matt or matt finish. Colour stability can be kept up to 50 years, ensuring the panel will remain as vivid for decades, even in the harshest environments.

Artistic decoration of the enamelled panels is also possible. Almost any creative idea can be reproduced on the panels with extreme accuracy using serigraphy (silkscreen printing) or decalcomania (transfer of engravings or prints). Four-colour CMYK printing can also be used to create wave forms, curved profiles and other special shapes.

Excellent resistance to abrasions and scratches

With almost the same hardness as a diamond, enamelled surfaces are able to resist extremely abrasive conditions including sandstorms. Scratches, impacts and wear have no influence on enamelled steels.

Enamelled steels are also resistant to damage from flames or other sources of heat and have an A1 fire resistance rating. Even when heated, enamelled steels do not release any toxic fumes.

Outstanding resistance to corrosion and UV

As well as providing a range of colour and finish options, enamelled steel panels will resist:

• Atmospheric pollution (including sulphur dioxide and nitric oxide)
• Rain
• Salt-laden marine atmospheres
• Sudden changes in temperature
• Ultraviolet radiation
• Weather – enamelled panels are insensitive to extreme cold (-50°C)  and very hot temperatures (above 50°C)

Pollution-resistant

Modern-built environments are extremely susceptible to the effects of corrosive atmospheric pollution. However, enamelled steels have no pores or cracks. This stops bacteria, dust and pollution from gaining a foothold in the enamel.

Enamelled surfaces are very easy to clean. Most commercially available solvents can be used without affecting the colour or finish. Even graffiti can be easily removed from the enamelled surface.

Recommendations for use

Deformed parts such as profiles and cassettes can be made with ArcelorMittal’s adapted steel grades including Solfer®. As well as being ready for enamelling, these grades can be assembled like other facade products.

The long-term maintenance of enamelled panels is simple. During renovations it is easy to perfectly colour-match panels as there should be no noticeable differences between old and new panels.

Other applications for enamelled panels include:

• Facade envelopes
• Interior design
• Public transport buildings such as airport terminals, railway and subway stations
• Sunscreens
• Tunnels
• Special projects

ArcelorMittal can advise you on the most suitable grade to fit your project budget and the level of quality required.

ArcelorMittal has developed powerful computational tools which can simulate the vitreous enamelling process and help you to design your facade elements. Computational simulation techniques are especially useful for defining the right shape and thickness of panels. Do not hesitate to consult our technical or R&D experts for more information.

The Mall of Egypt is an ambitious retail and leisure project under construction in the city of Cairo. Apart from retail and restaurant spaces, the supermall will also include the first ski park and 4D cinema in northern Africa. ArcelorMittal supplied Hacierco decking profiles, provided special calculations and technical support.

Developed by UAE-based retailer Majid Al Futtaim (MAF) Properties, the Mall of Egypt will offer a usable surface of 162,500 sqm on two levels, 400 retail shops featuring a range of international fashion and lifestyle brands throughout the mall and the open air plaza, a ski park with a 250 m slope, a 17-screen cinema, a family entertainment centre and over 50 food and beverage outlets.

The Mall of Egypt is being built on 399,400 sqm of land outside Cairo close to the Al Wahat highway. Access will be granteded directly off the highway via a bridge, the facilities include a car park with 6.500 parking spaces.

The mall is designed according to modern sustainability requirements and strives for LEED Gold.

Construction works started in 2013 and are expected to be completed by the end of 2015, inauguration is planned for early 2016.

The Mall of Egypt, a sister brand to MAF Properties’ "Mall of the Emirates" represents a total investment of EGP4.9bn (US$800m), the construction phase has created 9.000 jobs and once the mall is opened, 7.000 people will work there.

Orascom Construction and BESIX Group have been awarded the US$400m construction contract in a  50/50 joint venture.

Despite of the country's ongoing political and social unrest, the developer has been commited to the project and confident in the Cairo market and it had not seen any decline in demand for space. In fact, according to an article on arabianbusiness.com, 70% of the retail space were already been pre-let shortly after ground breaking.
