Recently, a wide variety of steel-wood doors have flooded the market, with prices ranging from just a few hundred to several thousand dollars. On the surface, they may look similar, but the materials used can vary significantly. When purchasing a steel door, it's crucial to pay attention to specific details to ensure quality and safety.
Focus
Two years ago, the home decor trend leaned toward a simple black-and-white style. I chose a white steel-wood door, but within a year, various issues arose. First, after installation, there was a faint pungent smell in the house, and occasionally my eyes would feel irritated. Later, when moving furniture, I accidentally bumped into the door, causing a small dent. I want to ask an expert: are there environmental and quality problems with these types of doors?
Identification
The thickness of the steel plate on a steel-wood door should not be less than 5mm, but many products on the market fall below this standard. Steel-wood doors were once very popular, but their filling is often a mix of wood and other materials. If you can smell a strong odor, it might indicate that the wood quality is poor and that formaldehyde, benzene, and xylene levels could be excessive. Additionally, if the outer steel layer is too thin, the door may warp or deform upon impact. However, salespeople rarely highlight these details during the purchase process.
It’s generally not recommended to use steel doors throughout the entire house. For bedrooms, study rooms, and children’s rooms, more environmentally friendly wooden doors are better choices—both aesthetically pleasing and safer for health, though they tend to be more expensive.
Despite these drawbacks, steel-wood doors do have clear advantages. For example, even after two years of use, a bathroom door remains undamaged by humidity, and the sound insulation is excellent. Watching a movie at night in the living room won’t disturb the elderly. Therefore, despite their flaws, steel-wood doors still maintain a steady presence in the market.
Recently, there have been many new steel-wood doors on the market, priced from a few hundred to thousands of dollars. While they look similar, the materials used can differ greatly. It's important to carefully examine the details when buying a steel door.
The first thing to check is the surface paint. The topcoat of steel-wood doors typically comes in two types: PVC and baking varnish. PVC offers a good finish and appearance, which is why it's commonly chosen by consumers. However, the cost difference between PVC and baking varnish is only a few tens of yuan, yet the latter has better durability and is less likely to peel off over time.
Next, consider the frame. Steel door frames usually come in sizes like 4cm, 8cm, 10cm, and 12cm. You should choose the size based on your wall thickness. Some smaller brands promise full installation, but using an 8cm frame on a 12cm thick wall will result in an unattractive gap. In some cases, if the wall is thicker than expected, additional charges of around 30–35 yuan per cm may apply. It’s best to clarify this before making a purchase.
Also, check the thickness of the steel plate and the quality of the filled wood. According to national standards, the steel plate thickness should not be less than 5mm, but many products on the market don’t meet this requirement. As for the wood filling, there are currently no strict regulations, so the environmental impact and moisture content of the wood directly affect the overall quality of the door.
Therefore, when signing a contract for a steel door, it's wise to include specifications such as the steel plate thickness, wood quality, and frame size. This helps avoid future quality issues and ensures you get what you paid for. Of course, purchasing from a well-known brand provides greater assurance and peace of mind.
