There are many considerations to balance when deciding which trims are the most suitable. Fortunately, Profilitec’s excellence at designing and manufacturing in a number of materials enables us to offer a great range of products to suit even the most demanding project.
Consider carefully the environment the trims will be installed in. Choosing the right material for tile trims and profiles can be important. Here we explore two key considerations for each type of material used to manufacture Profilitec trims; mechanical properties and chemical resistance. Please contact us for further guidance.
Stainless steel trims (Grade 304 or Grade 316)
Stainless steel trims are regarded by many as the highest quality profile/trim. They have the advantages of;
- Being more durable with high mechanical strength, and having resistance to abrasion and force (dents) than profiles made of softer material
- Resistance to water, water vapour, resulting humidity and weak organic and inorganic acids.
- Polished products increase the resistance/ improve hygiene by reducing the surface area.
- There are special trims available in Grade 316 stainless steel which are acceptable for use in a swimming pool environment (note that the trims made from Grade 304 stainless steel are not suitable for swimming pools).
While stainless steel trims are more expensive, many regard the price as one worth paying for longer life/durability. Stainless steel is particularly favoured in chemical, food processing and medical/hospital environments.
Aluminium trims in various finishes
Composed of a primary alloy, the material is hot tempered making it suitable for more complex extrusion processes.
When you are using trims, please ensure that the trim/profile surface is protected during tile laying to avoid adhesive contamination or scratching.
Anodised aluminium trims
Anodizing of aluminium ensures that the surface is well protected against corrosive influences. For this reason, these profiles are also very good for general purposes, such as a bathroom. Profiles are treated to become uniformly matt and electro-chemically oxidized and coloured to a depth of 20 microns in the standard silver, gold, bronze, copper and titanium.
The mechanical strength of the protective layer is limited and for this reason these profiles should not be used in high impact areas, or in areas which are highly polluted.
Trims made of bright polished aluminium
Offered for gold, silver and titanium polished finishes. The product maintains the same mechanical and chemical resistance as the anodised version with an attractive bright appearance which makes it look like gilt or chromed surfaces. There are the same limitations as to where to use these trims/profiles as the above Anodised trims.
Trims made of coated aluminium
The protective layer of the aluminium is an electrostatic process applying a polyester powder coating 60 microns thick. The advantages of this method are that the colour fastness by heat impression supplies greater resistance to mechanical impact as well as greater chemical resistance.
Trims made of brass
Brass profiles are characterised by a high tolerance to mechanical stress which leads to them being regularly specified for flooring and coverings with intense traffic, like industrial applications and used as expansion joints.
Brass also offers a high resistance to chemical agents normally present during tile laying. In areas of high humidity, brass can suffer from oxidisation and consequently darken. Spotting can be easily removed with a conventional polishing product to bring it back to its original shine.
Trims made of polished brass
The polishing finish is performed by special buffing machines. Over time the surface of the metal may suffer slight oxidisation but spotting can be easily removed by using polishing agents.
Trims made of chromed brass
The chrome effect is achieved through a galvanisation process which confers a stainless steel like shine to the brass. While the material has high resistance to chemicals, it offers limited resistance to mechanical impacts on the surface and to persistent abrasion.
Trims mode of thermoplastic synthetic resin
Profilitec manufacture trims from a variety of plastics. We recommend the trims are used only in the decorative areas, such as a wall profile. Please do not clean these with abrasive cleaners otherwise the surface can become roughened and dirt can accumulate.
Trims made of RESINTOP rigid thermoplastic
A rigid plastic profile for permanent installations both indoors and outdoors to guarantee both endurance and aesthetic quality over time.
It is UV resistant and tolerant to mechanical impact as well as fungus and bacterial concentrations.
Trims made of RESINIL thermoplastic
Primary resin material with characteristics similar to RESINTOP above.
Trims made of RESINFLEX soft thermoplastic
This bears similar chemical properties as the RESINIL above. The plastic properties allow it to remain elastic over time, making it suitable for manufacturing expansion joints.
Trims made of RESINPRENE vulcanised rubber
This is a modified NEOPRENE based product range which offer excellent mechanical performance in extreme temperature ranges from -40C to +150C.
The material is also resistant to water based fluids, oils, hydrocarbon substances and lubricants.
It has low permanent deformation to compression and tensile strength.
Excellent resistance to aging.
It is a hard-wearing product and can withstand lacerations.
The foregoing qualities make the material particularly suited to manufacturing trims where long-lasting performance are required for both indoor and outdoor applications.
Resistance to common elements
