Frequently asked questions
Answers about invisible grills, materials, safety, installation and pricing in Visakhapatnam.
General
What are invisible grills made of?
Thin, high-tensile 316 marine-grade stainless steel cables with a nylon coating, fixed into aluminium channels at the top and bottom and tensioned so they stay straight and firm.
How much do invisible grills cost?
Price depends on area in square feet, cable thickness and the gap between cables. We give an exact quote after a free site visit and measurement.
How long does installation take?
Most balconies and windows are completed in a few hours to one day. Larger terraces or multiple openings may take longer, we confirm the timeline with your quote.
Are invisible grills safe for kids and pets?
Yes, that's what they're designed for. Narrow vertical spacing prevents children and pets from slipping through, and the smooth cables give nothing to climb on.
Do they rust near the sea?
No. 316 marine-grade stainless steel is made for Vizag's salty, humid coastal air and heavy rain. An occasional wipe with fresh water keeps them looking new.
Do you also install pigeon nets and cloth hangers?
Yes. Along with invisible grills we install pigeon safety nets and ceiling cloth hangers, and can plan all three in one free site visit.
Which areas do you serve?
We install across all of Visakhapatnam, from Bheemili, Madhurawada and Rushikonda to MVP Colony, NAD, Pendurthi, Gajuwaka and the Steel Plant area. Message your locality on WhatsApp to book a visit.
Balcony Invisible Grills
Will invisible grills stop a child from climbing over?
The cables run vertically with a small gap, so there is nothing to step on and no space to squeeze through. They are designed to prevent falls, not to be climbed.
Can I still dry clothes or keep plants on the balcony?
Yes. The grill sits along the outer edge of the balcony, so the full floor space is still yours.
Do I need permission from my apartment association?
Many associations allow invisible grills because they don't change the building's look. It's worth checking once, we can share product details for the approval.
Window Invisible Grills
Can the window still open and close?
Yes. The cables are fitted across the opening, so the window works normally.
Is it strong enough for a high floor?
Each 316 stainless steel cable is high-tensile and anchored into a secure channel. We recommend thickness based on the opening size and floor.
Staircase Invisible Grills
Can you fit cables on an angled staircase?
Yes. Channels are cut to follow the slope and each cable is tensioned individually.
Will it damage my existing railing?
Fixings are small and placed neatly. We check the railing and mounting surface during the free site visit first.
Terrace Invisible Grills
Do terrace grills need posts?
If the parapet is low, slim posts are fixed to hold the top channel. We suggest height and spacing after measuring.
Will cables loosen outdoors?
Each cable is tensioned during installation and can be re-tightened if needed. Materials are made for outdoor use.
Duplex & Void Invisible Grills
Can cables run floor to ceiling in a void?
Yes, for full-height protection cables can run between floor and ceiling channels. For railing-height protection, a top channel is fixed to the railing or posts.
Is it safe for a play area on the mezzanine?
That's one of the most common reasons people install it. We use closer spacing where young children play.
Child Safety Invisible Grills
What spacing is best for small children?
Closer spacing is recommended for toddlers. We suggest the right gap after seeing the opening and the age of your children.
Can children hurt themselves on the cables?
The cables are nylon-coated and tensioned straight, with no sharp ends exposed.
Pet Safety Invisible Grills
Can a cat get through invisible grills?
With standard spacing, a small cat may. For cats we use tighter spacing and seal the side edges. Tell us about your pet when you book.
Will my dog be able to chew the cables?
The steel core is very strong. The outer coating may show marks if chewed often, so we suggest training or a lower guard if needed.
Sea-Facing Apartment Invisible Grills
Why 316 and not 304 stainless steel?
316 contains molybdenum, which gives it better resistance to salt and chloride corrosion, the right choice near the sea.
How do I clean them?
Wipe the cables occasionally with a damp cloth and fresh water to remove salt deposits. That's all they need.
Pigeon Safety Nets
Will a pigeon net block light and breeze?
No. The mesh is fine and the net is tensioned, so light and air pass through easily and it is hard to notice from inside.
Can pigeon nets and invisible grills be installed together?
Yes. Many families use invisible grills for safety and a pigeon net to keep birds out. We plan both in one site visit.
Is the net harmful to birds?
No. The net simply blocks the opening so birds cannot enter or nest. It does not trap or injure them.
Ceiling Cloth Hangers
Is a ceiling cloth hanger safe to use?
Yes. It is fixed into the ceiling slab and operated by a pulley rope, so you never need to climb or lean over the railing.
How many pipes can I get?
Pipe count and length depend on your balcony size. We suggest a layout during the free site visit.
Will it work with invisible grills?
Yes. The hanger sits on the ceiling inside the balcony, so it works alongside invisible grills and pigeon nets.
