Sine wave - Import export

The Poppe + Potthoff impulse test stands test the operating or fatigue strength of various metal and plastic components. The endurance test in our high-pressure test systems simulates the life-cycle under varying loads. The failure tests thus show the potential weaknesses of the components with respect to design and material. The pressure is optionally modulated as a sine wave, trapezoid curve or needle pulse. Our test stands are characterized by a special ergonomics and are designed by Poppe + Potthoff machine design. Due to our flexible modular design, our machines are very variable, so that the pressure and volume range is designed according to the customer’s requirements. Of course, our systems are UL or CE compliant as required. In addition, we offer you service and support directly on-site.

For roof-construction in industry and commerce, Panelsell Ltd are able to provide sheets in various thicknesses and lengths. Increasingly instead of profiled sheets (uninsulated trapezoidal sheets), insulated roof panels are used. These panels consist of an upper and lower sheet, which are usually made of galvanised painted steel. Standard thicknesses tend to between 0.4mm to 1.0mm, which can produce different strengths as needed. It is also possible to have the outer and inner sheets made from aluminium or stainless steel.In areas exposed to a heavy stress due e.g. to ammonia, ECO panels are also used, as an alternative to insulated roof panels with a galvanised inner surface made of steel sheet. The inner surface of these panels is made of stucco embossed aluminium foil. In addition, these roof panels are cheaper than conventional roof panels. Insulation tends to come in both polyurethane and polyisocyanurate (PUR and PIR) as well as rockwool (also known as mineral wool). Decision for the choice of insulation takes into account for flammability and resistance, or structural characteristics such as themal and moisture protection. The roof panels often have a trapezoidal box profile structure. There is an alternative option of corrugated profile (shaped in a sine-wave) and traditional tile aesthetic.. On request, we can offer you the full range of insulated roof panels. This is in accordance to your requred length, thickness and most RAL-colours. Of course, we can also offer special offers and cancelled ordesr that has been returned to site..
