Reinforcement steel 28 mm according to DIN 488 – standard and marking

Concrete bar 28 mm is manufactured according to the DIN 488 product standard. The standard regulates steel grade, ribbed, dimensional tolerances, mechanical properties and marking. The B500B grade steel we have supplied has a characteristic yield point of 500 N/mm² and a high deformation capacity (ductivity class B), which is important for the announcement of failure in the case of load-bearing components. Each staff carries a rolled-in marker that encrypts the manufacturer’s works and the country of origin, as well as a valid certificate of conformity. Details of the standard are explained by the guideReinforced steel according to DIN 488 – standards explained.

• Steel grade:B500B according to DIN 488
• yield point:500 N/mm²
• ductility:High Ductile (Class B)
• Rib:Standardized for composite with concrete
• proof:Work certificate / proof of conformity

Reinforcement steel applications 28 mm

The diameter of 28 mm is mainly used in reinforced concrete construction for large components, bridge construction and bored piles. The choice of the correct diameter results from the static calculation of the structure. Typical areas of application:

• Highly stressed foundations and floor slabs
• Supports and beams with large loads
• Boring piles and reinforcement baskets
• Bridge and Civil Engineering

For the right application, we supply the steel straight cut or as a curved bending form according to your reinforcement list. Our site offers an overview of the entire rangereinforcing steel.

Bending and Cutting Reinforcement Steel 28 mm

Concrete bar 28 mm can be bent according to DIN 488 if the minimum bending roller diameter is observed. For 28 mm, this is 12 D to avoid damage to the steel and cracking. We manufacture brackets, bends, hooks and complex bending shapes according to your bending list and deliver accurately positioned commissioned to the construction site. This eliminates bending and cutting on site and the assembly time is significantly reduced. All services can be found atBending & Cutting.

Concrete cover and laying

To ensure that reinforcement steel is permanently protected against corrosion 28 mm, the concrete cover according to Eurocode 2 (DIN EN 1992-1-1) must be observed. It is made up of the minimum C_minand a precaution Δc_dev(usually 10-15 mm) and depends on the exposure class of the component. When laying, spacers ensure the planned position of the reinforcement; Shocks are executed over the required overlap length. Binding wire fixes the rods in the formwork.

Quality, test certificate and traceability

Our 28 mm reinforcement steel is supplied with a valid work certificate (acceptance test certificate 3.1) which proves the mechanical and technological properties as well as the traceability via batch and melting number. This gives you standard-compliant, testable reinforcement steel, which meets the requirements of DIN 488 and Eurocode 2 – from delivery to installation verifiably.

Order rebar 28 mm and delivery

You order reinforcing steel 28 mm simply made to measure: specify length or bending shape, quantity (in meters, piece or bin) and the desired delivery date. We deliver throughout Germany – from the individual rod to the complete component reinforcement. A non-binding fixed price offer can be obtained from our pageContact. You can also find the basics of diameters and weights in theDiameter and dimension table.

Reinforcement steel 28 mm compared to diameter

In the range of reinforcing steel Germany, you can get reinforcing bars from 6 to 40 mm. The following table shows how reinforcing steel is classified in the overall program in terms of cross-section and weight – helpful if the statics choose between adjacent diameters:

A larger diameter means more carrying capacity per rod, but also higher weight and larger bending roller diameters. The same reinforcement surface can often be achieved either with a few thicknesses or many thin rods – the most economical solution depends on the installation effort, the bar spacing and the concrete cover.

B500A and B500B – which type for 28 mm?

Reinforced steel is supplied in the B500A and B500B grades according to DIN 488. Both have a yield point of 500 N/mm², but differ in ductility. As a bar 28 mm, we supply the high-ductile grade as standardB500B, which is suitable for load-bearing components with higher demands on elongation at break and hardening. B500A is mainly used for cold-formed wire and mat products.

Overlap and anchoring of reinforcing steel 28 mm

Shocks of reinforcing bars are usually carried out as a surge shot. The required overlap length is a multiple of the rod diameter and depends on concrete quality, composite conditions and bar spacing. The following orders of magnitude are used as a rough guide for reinforcement steel 28 mm (the relevant values always provide the static calculation according to Eurocode 2):

At 28 mm, an overlap of 50 × D corresponds to around 1400 mm. Too short shocks or bending radii that are too tight weaken the component – that’s why we manufacture bending shapes and joints exactly according to your reinforcement list.

Concrete cover and exposure classes

The concrete cover protects reinforcement steel 28 mm from corrosion and secures the bond. It depends on the exposure class of the component. Reference values for the nominal size of the concrete cover:

Processing, welding and storage

Concrete bar steel B500B is welded to conditionally suitable for the carbon equivalent (CEV); The rules of DIN EN ISO 17660 must be observed for load-bearing welded joints. Cutting grinders or bar shears are used when cutting. Store reinforcing steel 28 mm dry and jacked up to avoid rusting and dirt – slight rusty rust does not affect the bond, loose rust and dirt must be removed before installation.

We deliver reinforcing steel 28 mm throughout Germany and on request to Austria, Switzerland and Luxembourg. Whether single bar, cut positions, curved bending shapes or complete component reinforcement – the picking is done according to your list. Mat bundles and bars are delivered bundled and require crane discharge; We agree on a realistic delivery date in advance so that the construction process remains smooth.

Application examples for reinforcing steel 28 mm in detail

Where the diameter of 28 mm is specifically installed depends on the component and the stress. The following examples show typical applications in construction and civil engineering and help with material planning:

Foundations and floor slabs:In the case of high loads, reinforcement steel 28 mm takes over the main reinforcement of powerful foundation plates.Boring piles and reinforcement baskets:In prefabricated baskets, the large diameter bears the loads of deeply founded structures.Bridge and Civil Engineering:In abutments, pillars and troughs, 28 mm is used where cross-sections are highly exploited.

For prefabricated elements, we combine 28 mm reinforcement steel withreinforcement baskets,structural steel matsandplug-in bracketsto ready-to-install positions.

Quantity determination and calculation

For calculation and order, the steel quantity is determined by length and weight per meter. Computing example for reinforcement steel 28 mm: If 25 rods of 6 m each are required for each component, 150 m of steel results. At 4.834 kg/m, this corresponds to 725 kg or around 0.73 tons. With this simple calculation, positions from the reinforcement plan can be quickly converted into order quantities and costs; Reinforced steel is usually traded per ton.

• Total length × weight/meter = position weight
• Position weight ÷ 1,000 = weight in tons
• Schedule a surcharge for overlapping shots (approx. 10-15%)
• Consider waste at standard lengths

Standards environment: DIN 488 and Eurocode 2

Reinforcement steel 28 mm is in the interaction of several sets of rules. TheDIN 488is the product standard for reinforcing steel and regulates varieties, dimensions and markings. TheEurocode 2 (DIN EN 1992-1-1)Controls the design and execution of reinforced concrete components – i.e. concrete covering, anchoring, overlap and minimum reinforcement. DIN EN ISO 17660 applies to welded joints. Anyone who plans and executes according to these standards will receive stable, durable and testable reinforcement.

Avoid common mistakes when using reinforcing steel 28 mm

• Too low concrete cover → risk of corrosion
• Too tight bending radii below the minimum bending roller diameter → Steel damage
• Too short overlapping lengths → component attenuation
• B500A and B500B confusion for load-bearing components
• Missing item numbers on the bending list → Assignment error on site
