Productdescription 

CPL is the registrated brand name for (C)orrugated (PL)ate of Corrugated Plate Industry BV

 

Useable material for Corrugated Plates 
  • Steel S235JRG2, S355J2G3, LGA (Lloyds Grade A)
  • Aluminum 
  • Stainless Steel 

Tolerances: by DIN EN ISO 13920-CG, length tolerance +0 till -5 mm

 

Patented Production Process 

Our patented production process doesn't require moulds and therefore we are able to manufacture all dimensions between module 500 mm and 1000 mm. In our standard configuration the angles are 45 . Angles till max 70 can be achieved.

Why Corrugated Plates ?
A corrugated plate is an example of a 3-dimensional or space structure. Corrugated plates have enhanced resistance against horizontal and vertical loads. To consider the effectiveness of corrugated plate look at the following experiment.

Enhanced horizontal resistance

When a thin sheet of steel rests between two supports it will bend due to the fact that it has insufficient strength to carry its own weight.



If the same piece of steel is corrugated then it will be capable of supporting one hundred times its own weight.

 

If the load is increased past this point then the structure will fail and the corrugations will flatten out.

 

This problem can be rectified by using transverse stiffeners at the ends. The corrugated plate acts as a beam and can support even greater loads.

Enhanced vertical resistance

When a thin sheet of steel is stressed to a vertical load, the plate will bend due to the fact that it has too less capacity.


The profiling of the plate avoids failure, due to enhanced resistance against vertical loads.

Corrugated Plate dimensions

The figure below shows our standard corrugation. Other dimensions are also possible. Please contact us.

Our patented production process doesn't require moulds and therefore we are able to manufacture all dimensions between module 500 mm and 1000 mm. In our standard configuration the angles are 45 º. But angles of approximately 70 º can also be achieved.

Our corrugated plates are unlimited of length. The plates have no theoretical limitations in the number of folded modules.


The folded modules have to be transported, so in practice the lengths are ranging between 6 m and 18 m.

Corrugated Plate shapes


There are several varieties of corrugation shapes. All shapes which continuously repeat can be manufactured by GLP. The only condition is a maximum depth of 240 mm.

Corrugated Web Beams

A Corrugated Web Beam or a GLP Beam is a built-up girder with a thin-walled, corrugated web and plate flanges. The profiling of the web avoids failure of the beam due to loss of stability before the plastic limit loading of the web is reached.
Engineers have long realized that corrugations in webs enormously increase their stability against buckling and can result in very economical designs. Therefore, Corrugated Web Beams have the potential to eliminate many costly web stiffeners. In addition, the use of thinner webs results in less raw material cost with savings estimated at 10-30% compared with conventional built-up sections and more than 30% compared with standard I-beams.
The optimum area of application is in steel structural engineering wherever rolled profiles of structural height greater than 800 mm or lattice girders above 1500 mm were formerly used.
Within the subject of girders there are again many applications.

For fatigue applications such as bridges etc., it is thought that sinusoidal corrugations are better than trapezoidal corrugations. This is not the case for GLP corrugated plates. GLP is able to bend the plates with a radius/thickness rate greater than the number 5.

 
   

Applications

Corrugated web beams are manufactured to meet the markets highest requirements. The beams and the corrugated plates are suitable as:

  • supports and columns
  • steel retaining walls
  • transportation structures (such as the side panels of trains, containers and trucks)
  • feed silos
  • cranes
  • double-hulled ships


Conveyer belts

 


Floorbeams



Hybrid Construction
The aim is to take advantage of different materials. The concrete is used for the deck and the bottom slab. The webs have only to connect the cross section and to transfer the transverse forces. For this a corrugated plate is used.
