Say PVC and most buyers think of window profiles. The PVC on a door is a different product entirely: a printed foil roughly 0.3 to 0.6 mm thick with an adhesive backing, drawn onto a shaped MDF face in a vacuum press under heat and suction. Softened by heat, the foil wraps every groove and radius of the panel and holds that form as it cools. Almost all of the deep embossing, carved panelling and fine laser detail you see on steel doors is surfaced this way.

How it is produced

The MDF panel is CNC-machined first, which is where pattern grooves, edges and radii are cut. The face is sanded and dust-extracted, because residual dust becomes a bond failure. Adhesive is applied, allowed its open time, and panel and foil enter the vacuum press. Excess foil is trimmed and the edges routed before the panel is fitted to the steel leaf. Most defects originate in the press step: too short a cycle and the foil never seats at the bottom of a deep groove, which later whitens or lifts. Press a fingernail into the deepest point of the pattern and you can feel whether there is a void.

Why it dominates the market

  • The widest pattern library: wood grain, solid colours, marble, concrete, metallics and textures from one process.
  • It follows three-dimensional form; no other cladding wraps deep carving as cleanly.
  • Non-porous, easy to clean, stain resistant.
  • Scratches show less than on paint because the foil carries its colour through.

Our laser-cut embossed PVC steel doors push this technique hardest, where pattern depth and foil elasticity have to work together.

Where it fails

The foil is waterproof; the MDF beneath it is not. The risk sits at the edges, not the face: the handle-side edge, the bottom rail and the glazing frame junction. If edge closure is weak, water reaches the MDF, the panel swells and the foil lifts. That is why membrane-clad doors do not belong on exposed exterior openings, uncanopied villa entrances or rain-facing facades, while a sheltered apartment stairwell causes no trouble. Heat sets a firmer limit: a dark membrane face in direct summer sun reaches temperatures that soften the adhesive, so exposed south-facing openings move to laminate or composite panels instead.

Edge closure matters

Three methods exist. Wrapping the foil around to the rear is cheapest and most vulnerable. A PVC or ABS edge band leaves a visible fine line but performs better. Aluminium or stainless edge profiles are the most durable, the most expensive, and often used as a deliberate design detail. For a high-traffic entrance, ask which method was used.

Batch consistency for export orders

Foil arrives in rolls and print tone can drift slightly between rolls. A single door buyer never notices; a buyer installing two side by side does. For double-leaf sets, ask that both leaves be cut from one roll. Also specify pattern direction: on wood-grain foils the grain should run continuously along the leaf rather than break panel to panel. One line in the order, such as grain vertical, prevents a dispute later.

Cleaning, repair and shipping

A damp soft cloth and neutral detergent are all that is needed. Thinners, acetone and chlorine-based cleaners dull the surface, and abrasive pads polish the high points of the pattern. Small cuts can be filled with a coloured wax stick, but membrane has no real repair route: visible damage means replacing the panel, which is why the finish code needs to stay on file. Deep rustic textures such as those in our rustic laser-cut steel doors need the pattern and foil chosen together. Panels ship from Istanbul crated with corner protection; send your openings in centimetres and the exposure of each one and we will quote against your measurements.
