Honestly, I'm sorry to say that your pole doesn't sound safe at all.
Pole dancers have to be very careful with the quality of pole that they dance on, because we are trusting our full weight and safety on them. Without the materials and serious strength in the pole, any kind of exercise upon the pole where it carries your weight, including a spin or climb, could be a serious risk.
Most poles do look very much the same- Lil mynx sells poles that are powder coated, and can be many colours, including black, red, and pink. My own is purple.
Many other poles are silver, bronze, brass, and are sometimes made in one full, single piece, and sometimes made in separate pieces that you link together.
But, despite these similarities, many poles exist that are of inferior build quality, as well as inferior materials. It can be extremely dangerous, as many poles masquerade, and even advertise that they are adequate for inverted moves and spins. The most notorious for this is the Peek a Boo pole, or the Carmen Electra pole made by the same company.
Most people will only purchase a pole from one of three companies: Lil Mynx, X Pole, or Platinum stages. Depending on your preferences about how your pole is made, and how it is put up in your home, you can choose from there. I, personally, enjoy Lil mynx poles, and many other people here prefer X pole. Otherwise, there is no actual standard for building of poles, and not often have I seen any other company create a safe pole.
I would seriously recommend looking into purchasing a new, safe pole. I realize it can be quite expensive, but your safety with this form of dance is very, very important. Injuries can really damage your progress, or perhaps even your permanent mobility.
