Lead-lined coffins slow the body's decomposition by keeping moisture out of the casket. Lead does not decay and so remains airtight, preventing decomposition, but also any smells and gases from being released; not something you want if multiple Royals are sharing a vault or may be moved in the future.
As Royal Family members are buried inside a chamber, rather than directly in the ground, their coffins are lined with lead in order to slow decomposition. The lead seals the coffin and prevents moisture from getting in, preserving the body for up to a year.
Following royal tradition, which dates back as far as the 1600s, the queen's coffin was lined with lead, which ensures that her remains stay intact for up to a year. This is because the lead makes the coffin airtight, stopping moisture from getting in and therefore slowing down the decomposition of the body.
The Queen's coffin was made for her more than 30 years ago, by the same firm that made the lead-lined casket in which the Duke of Edinburgh lies buried.
A zinc lined coffin is a casket that has had the inner structure lined with zinc in order to preserve the coffins integrity. Whilst the outer casket will biodegrade, the inner lining will remain intact for many more years.

As material in coffins, “lead helps keep out moisture and preserve the body for longer and prevent smells and toxins from a dead body escaping,” said Julie Anne Taddeo, a research professor of history at the University of Maryland.
Queen Elizabeth II will be buried in an English oak coffin featuring brass handles that were designed more than 30 years ago, and lined with lead. It is estimated the coffin weighs between 250kg and 317kg.
Coffins get tapered to conform to the shape of a human form. A coffin also has a removable lid while caskets have lids with hinges. Coffins are usually made out of wood and lined with cloth interiors. Unlike caskets, they do not have rails that make transportation easier.
Following the funeral at Westminster Abbey in London, the Queen's coffin will be transported to Windsor, where she will be buried alongside her parents and her late husband, Prince Philip. While her coffin will be decorated with jewels as she lies in state, the late monarch may only be buried with a select few.
However, on average, a body buried within a typical coffin usually starts to break down within a year, but takes up to a decade to fully decompose, leaving only the skeleton, Daniel Wescott, director of the Forensic Anthropology Center at Texas State University, told Live Science.
After 1 month, the liquefaction process commences. During this stage the body loses the most mass. The muscles, organs and skin are liquefied, with the cadaver's bones, cartilage and hair remaining at the end of this process.

The pallbearers hail from the Queen's Company, the 1st Battalion Grenadier Guards. 'It's their role to protect her body, both in life and in death, remaining in the Queen's Company until King Charles decides otherwise,' explained Major Adrian Weale to the PA.
Traditionally, when someone was buried in the Royal Vault the coffin was lowered into it through a special opening in the floor of St. George's Chapel during their funeral.
The rate at which this occurs varies depending on the type of casket, the elements in the soil, and its condition. Typically, wooden coffins may take a few years to collapse after being buried, while metal ones are more resistant and can last longer.
Can Couples Be Placed in the Same Coffin? While it may be possible if there is a big enough coffin and plot to accommodate the couple, there are many other logistical constraints that may not permit this to happen. Having a large enough casket for two may not be easily transportable.
Most modern caskets lock using a universal casket key owned by funeral homes, while older and more affordable models are typically sealed shut using simple metal latches or clasps. Caskets are primarily locked for symbolic reasons and to protect the deceased's body in transport.
Where will Queen Elizabeth II be buried? Her Royal Majesty will be laid to rest in the King George VI Memorial Chapel within St. George's Chapel at Windsor Castle.
Lisa Levinson, head of communications at the Natural Diamond Council, has told Metro: 'Her Majesty is an incredibly humble woman at heart who is unlikely to be dressed in anything but her simple Welsh gold wedding band to rest and a pair of pearl earrings. '
Coffins must not have any metal in them, except high ferrous metal such as iron and only when it is needed for them to be made safely. Zinc or lead lined coffins cannot be cremated.
Embalming is a process which has also long been used by Royals, involving preservative fluids being injected into bodies to delay decomposition.
More generally, royals are buried in their finest clothing and jewellery. This may include robes or gowns, gloves, shoes, hats, tiaras and other items of their regular clothing. Additionally, funerary jewellery such as rings, medallions, and brooches may also be provided.
