Manufacturing materials

This type of accessory is generally made of 2 materials which are the most commonly used. Each material allows you to give a striking and very elegant finish to the door knockers. Each one is explained below.

Wrought iron. This material has properties that give it great resistance, its designs despite being rustic, are extremely elegant. We recommend this material specifically for double doorknockers and if you plan to install them in haciendas or ranches.

Steel. It is very malleable, so it allows you to create aesthetic designs with shiny, minimalist finishes, despite being simple. It is ideal for you if you are looking for a simple doorknocker to place on the door of your house or flat.

Type of door

It is not only important to consider the door knocker, but also where you want to place it, as the door is vital to get the most out of this product. On the other hand, the sound emitted by each door in combination with the right door knocker will make you hear it no matter where you are.

Slim door. It is the most used nowadays for the entrance of any house or flat. Its thickness is an average of 3 cm. And what it seeks is to protect your property from any external factor. We recommend a simple steel knocker if you have a door with these characteristics. In addition, it provides a soft sound, suitable for closed places such as a flat.

Wide door. Nowadays it is not very common to find this type of door in the city, however, in the countryside they are very popular. It has a thickness of between 15 and 20 cm. We recommend a wrought iron double knocker for this type of gate, as they emit a much louder sound, which can reach every corner of the property.


The most common designs for this type of product are two and each one offers the door knockers unique specifications and features. This is to obtain the ideal accessory for your entrance door. Therefore, we will focus on explaining each of them to you.

Rustic. It is widely used by country lovers, as the style of the furniture is based on wood and wrought iron. We recommend this design for haciendas and ranches and specifically for double doorknockers.

Minimalist. This is a much more aesthetically pleasing design with prominent details along the door knocker. If you have silver furniture with glass and particularly in the city, focusing on houses or flats, this design is ideal for you.

Double doorknockers are usually used on haciendas or ranches. (Olga Berlet/
